is it illegal to sell sodium and calcium?

I know sodium and calcium are both strong alkalines and make hydrogen gas and ignite it when put in water. So is it illegal to sell it completely or do you need to have a license.

Is Calcium Chloride safe to use on roof or gutter ice dams? Answered

In cold climes, snow buildup on roofs often leads to ice dams, usually at the gutter. When the snow melts, the dam can route water under roof shingles and cause roof damage.Is Calcium Chloride safe to use on roofs? (Sodium Chloride is not, due to it's corrosiveness.)

Which chemical have I made? Answered

After my experiment which turned out to be lead oxide, I did something else. I bought a lump of Calcite, and found out it dissolves in acid. Therefore, I couldn't resist breaking off some lumps and putting those in vinegar. For at least a week, there was no significant change in the container, but after another week, all of the vinegar was gone, and no sign of the calcite lumps either. only a white and a pink residue. What I want to know is, is this Calcium? Or something else?

Calcium Chloride Corrosive Effects

I know that calcium chloride can corrode metal, but does it require direct contact or can it generate fumes that could corrode?   Here's the issue:  I have a wood stove and I place a container of Damp Rid inside over the summer to absorb moisture.  It looks like the Damp Rid plastic container had a small crack, so moisture passed through the calcium chloride and through the container and through the back of the stove After a while I noticed a pool of water behind the stove.  I traced the problem back to the Damp Rid container, cleaned up the moisture inside and outside the stove, and replaced the Damp Rid.  At the same time I noticed areas all over the exterior of the stove where the finish was coming off, areas that were not in contact with the water.  In fact, at least one section of the stove that had direct contact shows no sign of  a problem. I'm trying to discover if the calcium chloride caused the problem, or if it's something else causing the damage.

using calcium chloride as humidity reducer closets /laundry rooms

I bought a product called "damp rid "in a hardware store that was used for removing moisture from hamper area,laundry rooms, to prevent mildew. i realized the pelted looked familiar and it was calcium chloride. i want to make my own as i have access to a big bag of calcium chloride. it looks like there is a piece of tyvek/ or other moisture passing membrane on one side of the top upper half, the other 3 sides of the bag look like a mylar  type bag.  The seams all seam to be sealed, except the top has a piece of plastic snapped-sea;ed over it, with a couple very small holes that go into the top half of the bag. the top plastic piece  also has a hanger  loop.. when i bought it the calcium chloride was in the top hang and the bottom half was empty. There looks like a plastic seam weld separating the calcium from the bottom half, and i noticed that are a couple 1/4 inch gaps in the seam. the calcium, chloride draws the moisture out of the air and turns it into water, which falls to the bottom half of the bag.pretty cool device, and seems i t would be able to make, if i can find a source for mylar or whatever this material is. i would also have to make the seams, not sure if glue would work, maybe make a clamp like device , rather than the welds, this way i could just empty the water and replace the calcium chloride, no reason to throw it out. anyone seen these devices, i noticed they have a www with the same name, they may have pictures.  Also looking for a source for mylar and tyvek.  I am not sure if the postal envelopes would work, i would also like to scrounge a sheet of tyvek to use as a ground-cloth or emergency shelter when out on my bicycle and the t storms hit. i haven't seen it except in big rolls, i guess i should keep a lookout for construction sites trash areas.otherwise i am not sure where  i could get a 10 ft piece. i will take the bag apart later to dissect the workings and see if i can measure the thickness of the  mylar

How do you make your own handmade paper "acid free"? Answered

While there are a few archival sprays that reduce the degradation and yellowing of paper after the fact, that is not what I'm looking for. I'm curious as to whether I can add something to the pulp in the process of handcrafting my own paper. I've heard that adding calcium carbonate while it's still in a slurry can neutralize the acidity of the lignin in the pulp. If so, couldn't I just throw a few Tums in there? And how much per batch?

can i make hydrogen sulfide by reacting a sulfide with oxalic acid?

Hi, i am trying to make hydrogen sulfide for the purpose of reacting it with ammonium hydroxide to create ammonium sulfide. however, since my parent think that concentrated hydrochloric acid is too dangerous to work with, especially since i can only get huge 20L bottles of it, i have decided to quest for a new acid to react with calcium polysulfide, to get hydrogen sulfide, thats when i came across solid oxalic acid. at first glimps, i saw that it said, hazardous, extremely corrosive acid, i thought "yes", this would work, i could react this with the lime sulfur , but then after some research i discoverd that no-one in the history of the world has ever documented the practical reaction of oxalic acid with a sulfide, in order to make hydrogen sulfide. so i want to ask , will oxalic acid, when mixed with calcium polysulfide, generate hydrogen sulfide? another reason though i might point out why i dont think oxalic acid will react with calcium polysulfide, is because it is a solid crystal acid, one that does not evapourate into gas like sulfuric or hydrochloric acid, and i cannot find anywhere documented either of non gaseous acids being able to react with calcium sulfide to make hydrogen sulfide, according to what i have found out, only nitric, sulfuric and hydrochloric acids will work. but this is also the reason i want to use oxalic acid over hydrochloric because i want to boil off the hydrogen sulfide through a tube and into concentrated ammonium hydroxide, but if there is hydrochloric acid in the solution, it would very likely boil off as well, which would be something of a hassle.

White stuff on my dishes. Not responding to anything yet. What is it?

The picture shows what I am talking about.  So far we have tried more heat, less heat, adding TSP to the detergent, cleaning out the dishwasher with one of those put it in by itself and run cleaning agents, turning on heated dry,, running with vinegar and detergent, running with vinegar instead of detergent, and using jetdry.  None of these things worked in any combination we have tried. The substance is dry and slightly slick if I rub it between my fingers. It is not calcium deposits, or if it is, they are mixed with something else. Other than that I don't know what it is.  It tends to stick to everything but less so to glass and moreso to plastic. Any ideas would be appreciated.

From my calculations, one could make the daily recommended equivalent (assuming no other food has said nutrients): Table Salt - 1 tsp (primarily: NaCl, gives sodium) Salt Substitute - 2 tsp (primarily: KCl, gives potassium) Milk of Magnesia - 1 tbsp (primarily: Mg(OH)2, gives magnesium) Antacid Tablets - 5 pills (primarily: CaCO3, gives calcium) This could be useful to endurance athletes and people who are practicing prolonged water-only fasting. Has any of you tried to make something like this before? What other essential nutrients would you include? Any recommendations for a phosphorus source?

Possibility of making temporary hair colouring?

Hello there, I've always wanted to dye my hair grey but didn't want to go through the hassle and the possible hair damage of bleaching.  I came across someone selling chalk sticks for temporary hair colouring and was wondering if a cheaper, liquid version could be made to cover all the hair instead of a small part. My initial idea was to use calcium carbonate and grey food colouring with maybe a little bit of talcum powder which will then be mixed with some water so it can be applied easier. These are the ingredients in the colouring I want to use: glycerol, propylene glycol, silicon dioxide, titanium dioxide, vegetable carbon  Is there anything here I should be concerned about? As I'm going for a grey colour I was also looking at using a small amount of activated charcoal or some other skin safe fine black powder. Is this the best way or are there better alternatives? Advice will be appreciated. Thanks for reading.

Potassium Nitrate

How i have been thinking about another concept of making potassium nitrate (used in black powder) from a garden fertiliser, potassium carbonate (k2co3). potassium carbonate can be bought from here in Australia at Bunnings warehouse so it should be available anywhere else. the other substance you need is any nitrate (eg. calcium nitrate). the metal in the nitrate should have 2 electrons in its outer shell so there are 2 potassiums and 2 nitrates. You dissolve both the chemicals in water but do not over saturate so there is solid on the bottom. next you mix the two solutions together. a solid should form and move to the bottom. then filter out the carbonate by pouring it through a paper towel and collecting the leftover liquid and throw away the filtered out solid ((metal) carbonate). boil off the water in the solution and then leave to dry. this should be potassium nitrate shouldn't it? any suggestions or criticism? reply back thanks.

Fire Extinguisher Case as a Water Bottle?

I went to test an old 2lb fire extinguisher we had by pressing the green test button and, it didn't work. The fire extinguisher was a BC type dry chemical fire extinguisher. The label reads (CONTENTS OF BC DRY CHEMICAL POWDER: SODIUM BICARBONATE, MICA, CALCIUM STEARATE, NUISANCE DUST, IRRITANT; HMIS 0-0-0.) I took the chemical out to use as crude sodium bicarbonate, and now I want to use the bottle. My plan is to keep the labels on, find a cap like they use on most aluminum water bottles, and clean the inside out really well. The question I have is, is it safe? It says the contents are non-toxic, but I would still want to clean it really well. What would I clean it with? Would I have to coat the inside of the bottle because of the metal, (powder coating type place) and if so, what type of coating? Thanks!

Just found out: Clean inside of a thermos - Simple!

I just had to clean my thermos prior the tournament tomorrow. A quick peek inside revealed some stubborn residue. Propably furring (chalky deposits) from the boiling water i use to make tea in them... (we have quite "hard" water with lots of calcium). The throat of the bottle (Full-metal thermos) was too narrow for normal cleaning-brushes... I fortunately had a bag of rice standing around and thought  "Hm... Hard and small things"! So i quickly added half a handfull of dry rice in the thermos and a bit of cold water (2-3 spoons). Then i shook it a bit and poured the rice out. The inside was quite clean and almost "pristine" again. This method should also work for thermoscans with glass-interiors. Another (better) way of doing that is propably (but ONLY if you have a METAL-Interior!) to add a hand of sand or fine gravel with some wather (Maybe even a bit of dishsoap) and give it a shake. Again: Only do the sand/gravel if your thermos does not have a glass-interior!! Have fun and enjoy a good drink while outside! :)

Yeast fermentation for composting solution?

I threw some hay off my lawn and some green weecds into a garbage can, some sugar and yeast and formented it to slug beer but the slugs did not like it. It then fermented further to vinegar, and a crust of green "Mold?" covered it. seems to have protected the vinegar from further fermentation. I tried a second bigger batch ( morning glory weeds) with less sugar but after a few days of good fermenting it went rotten and stinky. So there are probably thresholds for sugar content. Would the yeast be a way of adding fertilizer to organic gardens? Yeast can (I think) convert urea and nitrate to protein. Perhaps some green stuff has enough sugar to work without sugar addition. vine prunings? maybe. The first batch, i put bleach in to kill off microbes before I added water and yeast. Perhaps hydrated lime would work instead of bleach and also get the ph good for yeast fermentation. This might be a cheap way of liming your garden. (Here in victoria, hydrated type s lime is cheaper than limestone for garden addition. (But it contains more calcium!) The "yeast tea" or vinegar tea could be used on the garden and the weeds could then be transfered to normal compost or used as mulch. It might be an alternative way of using diseased materials of composting seedy weeds to kill the seeds. Brian

have i done anything wrong?

Today with my friend, i made a saturated solution of hydrogen sulfide by boiling aqeous hydrogen sulfide solution made by reacting hydrochloric acid with calcium sulfide. then what we did was we mixed the solution with ammonium hydroxide with hopes that as simply logic would predict, that we would get ammonium sulfide. now, the end result was nothing like ammonium sulfide, and was actually almost completely scentless, aside from the strong odor of exess ammonia, though we have not yet removed any of the mixed solution from its sealed container yet. i would like to ask, did we make ammonium sulfide suitable for use in a stink bomb? and if not, what did we do wrong? in multiple previous questions i have asked if hydrogen sulfide and ammonium hydroxide will mak ammonium sulfide, however, in all questions lemonie and others change the subject and spam the questions with warnings about the dangers of hydrogen sulfide, but refuse to actually answer the question, and so have forced me to go trial and error in the practical rather than the theoretical first. we do not plan on re-attempting the experiment until we know exactly what our outcome will be, which is , if we either mix a solution of hydrogen sulfide and ammonium hydroxide, or bubble hydrogen sulfide gas through ammonium hydroxide solution, will we get ammonium sulfide! also whoever best answers the question will recieve a best answer, also if you know any other ways to make ammonium sulfide, please do tell
