I have a waste solution of potassium dichromate (with some in the trivalent Cr state as well) and sulfuric acid. I want to reformulate and precipitate potassium dichromate.
Any ideas? mgilbert@caisc.com . THANKS

Whats the fastest and cheapest way to produce hydrogen? Right now I'm using sodium bi-sulfate and iron but its very slow, takes a few days to fill a Gatorade bottle.

a really fast method is aluminum foil and diluted hydrochloric acid (liquid pool acidifier) NOTE: DILUTED! though this doesn't produce chlorine gas if the acid is to concentrated you'll end up with boiling HCl.
Boiling hot acid accompanied by an acid steam is as bad if not worse than chlorine gas. So don't try it unless you're have experience handling acids.
A good test:
What is the difference between a strong acid and a concentrated acid?

Thanks for the help and I don't know the answer to that.

strong acids like HCl ionize completely when in water
> HCl => H+ & Cl-
weak acids don't ionize completely
concentration is just a measure of purity (or lack thereof)
as a side note all acids and bases are only such when dissolved in water
for an example refer to nurdrage's nitric acid instructable.
Science is just awsome! no?

very nice tutorial . I have some questions:
How can i test if my ammonium nitrate fertiliser its good enough to make sodium nitrate and potassium nitrate?(it was delivered with no info and in a normal bag without no brand name)
and
How can i purify my ammonium nitrate fertiliser without using methanol(rare and expensive in my country)?

I'm just starting to get into etching circuit boards for various electronic projects and was wondering if there was a way to replate a circuit board that didn't etch properly, or if there was a way to add copper to the other side of the board so that you could make a dual sided board.

the copper on a PCB is placed as a foil on the fiberglass while the resin is still wet.

dear nurdrage
I got a piece of magnesium one time and put it into a saturated solution of sodium bicarbonate. it started to fizz. no heat was given off, just some bubbles. after i took the magnesium out, and dried it, it had a purplish-black layer that could be scraped off with my knife. could you tell me what's happening?

ive got some problems.
im new at chemistry so i would like to ask a really silly question
a boiling flask or any other glass container ( made for boiling) will brake if i put it on my stove? if yes what can i do about it?
Yours,
Phevos

Yes it will break if you put it on the stove. Solution: Don't put it on the stove use a water bath or an oil bath. If you're dealing with danger and have any sick feelings...your feelings are correct. Science is fun when respected and deadly when not.

Could you possibly do a video on extracting metals like titanium and aluminum from household items?
Dear Nurdrage, I have enjoyed your many tutorials for chemstry, but wish you would make versions of them that we are able to download PDFs of. Its been hard trying to go back and forth between your videos and the actual lab. is there any way we can get you to rerelease some of your tutorials in step-by-step pdf versions? pretty please?

Dear NurdRage,
Im a chemistry major in College and I love what I do. Sadly, its hard to find some stuff for home experiments and hinders me outside of working in my classes predetermined labs, your instructables really help with solving that problem. Thanks so much for the help, keep up the great work!

Hello NurdRage. I did the experiment using the Potassium Iodide, Hydrochloric acid and Hydrogen peroxide, and was wondering if you could post the equations for the reactions that occur somewhere. Considering I'm only in high school, I was only able to use more dilute hydrochloric acid from a chemistry set, but the experiment still gave me a decent quantity of elemental Iodine :P nice video!

I have been playing with making a deep cycle battery from lead acid using Alum and distilled water for the electrolyte - the results look very promising but I am concerned as to what gasses I am creating within the battery. I have tried searching the web for information on this gas production, but have found nothing. Would you have any idea?
The battery is/was a standard lead-acid battery that I removed (and saved the sulfuric acid from, cleaned it out with baking soda and water and replaced the electrolyte with a 5% alum to distilled water solution.
The use of alum is said to be making this into a deep cycle "salt" based battery. The alum I used was standard grocery store variety but is supposed to be hydrated aluminium potassium sulfate. Any assistance will be greatly appreciated. Thanks!! BTW, Your instructables ROCK!!

The only gases that can be produced in this case are oxygen and hydrogen.
As for using alum to make a deep cycle battery. I personally have never heard of such a technique, and at first i would say it can't work since deep-cycle batteries use a different electrode design than high-current ones.
But i'm not an expert in battery design and if it works for you go for it :)

Thanks for the response, I will trap the gas for testing. Not sure if you are interested or not and I don't wish to take up more of your time if you are not, but if you have an interest, please visit:

He is incorrectly identifying the electrolyte as Alkaline - It should actually be a salt according to my research. BTW, I have cycled my test battery (converted lead-acid), about 8 times to well below 5 Volts and it still recovers quickly - and lasts longer each time (as stated in the text from the various forums). It is also stated that this is "non explosive", assuming that they are referencing Hydrogen, but as you can see - I don't believe everything that I read in this forum. I really do appreciate your educated opinion, and I don't take the term "explosive" lightly either.
As I said, I am not sure you even care (don't blame you in the least) but I was compelled to respond due to my gratitude to you for all of your hard work on these instructables, my hat is off to you Sir! Thanks again!

You should make a video on Nitrogen Triiodide. That would be exceedingly awesome. :)
we do not condone or assist in the making of high explosives. Also, NI3 has been done to death, it's unlikely we can do a better job.
