About:NurdRage is a dedicate group of science nerds trying to further amateur science with direct how-to instructions in video format. We saw what was already online and we thought "we could do better"... so we did. We have more videos on our youtube channel than on instructables since some things we do are less instructional and more just plain cool. So go to our youtube channel if you want to see more stuff than what we have here.

wow you are on instructables and youtube

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.

jonjones48 in reply to Jimmy ProtonJul 18, 2011. 4:40 AM

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?

Science is my life man!

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?

dear nurdrage
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

bazalaz in reply to phevtronNov 19, 2010. 11:15 PM

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?

funke75 says: Oct 23, 2010. 2:02 PM

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?
