I want to make Compost from a 55 gal plastic barrel that contained "Built Liquid Alkali", if washed will it be usable? Answered

 I recently acquired a couple of blue plastic 55 gallon barrels in the hopes of making my own rotating composter(s) and upon doing some reading via I-net found a lot of people saying "Only use food grade plastic barrels".  The barrels contained "Built Liquid Alkali", which is a silicated alkali builder designed for when combining with laundry detergent it makes for better soil removal and improves whiteness retention. Cautions read: Industrial use only, may cause burns, keep away from eyes mouth and skin. The first aid instructions are to use plenty of water to flush or wash affected area(s), leading me to believe that this is water soluble. I am hoping that possibly using OxyClean or some other suitable cleaner that I can make these barrels usable for what I need them for. If anyone has knowledge on this chemical and can provide some insight it would be most appreciated.

so you don't smell like vinegar? Answered

If you don't want to smell like vinegar, your can use a small amount of orange or lemon juice (pH of 2-3.5) to do the final neutralization of skin contact with strong alkalies (bases) like concrete or lye. It's a little more expensive, but does the job and leaves you smelling much better. If you don't have either of those handy, you can use almost any soft drink which are all acidic.

what are some easy ways to melt galena? Answered

I have found some Galena, an alkali metal ore containing silver and other metals, and am trying to melt it down to extract the silver to use in jewelry making. I have tried to melt some with a mapp gas torch with no success, it does not seem to heat enough that I can seperate the metals. Does anyone know of any cheap and easy solutions to extracting the silver without haveing to build a furnace.

How can I obtain cheap geosmin-scented air freshener?

What's the cheapest (safe and legal) way to obtain a small quantity of relatively pure geosmin? By "small" I mean an amount sufficient to keep a room smelling like rich earth for weeks. By "relatively pure" I mean it won't turn funky or give someone a nasty case of fungal pneumonia. Brew it? I know dehydration and alkali could -help- isolate Streptomyces, but then what? I don't have access to ready-made selective media nor money to buy strange supplies.

Extracting lead from car batteries?

I have a couple of battered old car batteries. There is no local scrap dealer that will take them so I was wondering if it would be possible to extract the lead myself and sell it for scrap. I have searched on google and cannot find anything about this and I suspect it would be dangerous and impractical. However I thought there's no harm in asking here. I was imagining that I could open the battery up and pour the acid into some kind of strong alkali, neutralising it to make it safe for disposal. But then, I certainly wouldn't like to try this without some advice first. Cheers! Pete

H202 production

Wondering if any one have come across a video showing the steps or know how to do this and how to extract H2O2 form the solution to make hydrogen peroxide like discribed from wikipedia article http://en.wikipedia.org/wiki/Hydrogen_peroxide#Manufacture i know i just cut and pasted to make it easer the history  barium peroxide with nitric acid. An improved version of this process used hydrochloric acid, followed by sulfuric acid to precipitate the barium sulfate byproduct.  Sodium peroxide also makes H2O2 Na2O2 + 2 H2O → 2 NaOH + H2O2 those are hard to come by for DIY and thought maybe this would easier  inorganic processes were used, employing the electrolysis of an aqueous solution of sulfuric acid or acidic ammonium bisulfate (NH4HSO4), followed by hydrolysis of the peroxodisulfate ((SO4)2)2− that is formed. peroxodisulfate commonly referred to as the persulfate ion hydrolysis is a chemical reaction during which molecules of water (H2O) are split into hydrogen cations (H+) (conventionally referred to as protons) and hydroxide anions (OH−) in the process of a chemical mechanism.[1][2] It is the type of reaction that is used to break down certain polymers, especially those made by step-growth polymerization. Such polymer degradation is usually catalysed by either acid, e.g., concentrated sulfuric acid (H2SO4), or alkali, e.g., sodium hydroxide (NaOH) attack, often increasing with their strength or pH.>

My grandparents found a rock at the beach that spontaneously combusted. what is it? Answered

My grandparents were out walking the dog before sunrise, and noticed an odd rock which felt warm, they left it, it was sitting at the shore line, not fizzling or bubbling, it was low tide,so it must have been submerged at one point within the last 4 hours. Later on their way back, the sun had rose and the rock was now fizzling , when they touched it with their sandal, it burst like a waterballoon of petrol and created a bright thick fire like an oil fire, as if the golf ball sized stone was filled with super heated napalm. My grandparents kicked the small stone which had not melted, into the water and it made a huge explosion which intensified the flames, as if it were sodium. My grandppa kept the stone after it had been burning in the shores wash line for an hour, and took it home. when he got home, he put it into a glass of water and it violently fizzled and sustained a flame momentarily. i checked the so called stone, and it looked like a standard beach pepbble with a tiny bit of quartz attached. What could it have been? that would have passivated in the water and not completely reacted until the inert skin was broken. my grandparents claim it was the sunlight that triggered the exothermic reaction. Anyway, they say the flames werent blidingly bright which possibly rules out alkali metals, plus it was yello which rules out lithium ontop of the meals, as well as the fact that it had previously been under water. does anyone know what it is? like i siad, it looks like standard smoothed beach rock now, its exterior was what burnt.
