Electroplating chemical mishap

I figured it would be cool to quickly electroplate some stuff. Since I was lazy, I only used what I had on hand [block of zinc, vinegar, muriatic (hydrochloric) acid)]. The zinc ingot was taking too long to dissolve in the vinegar, so I added about 30 mL of hydrochloric acid. A couple hours later, I was electroplating fine. After two weeks of normal zinc chloride electroplating, the acid suddenly took on a nasty dull brown/yellow amber shade and a ton of white bubbles formed around the zinc (still in the acid). Can anyone tell me what happened?

What is the best way to clean chemical bottles?

I was recently given a bunch of darkroom equipment including chemical bottles like this and this. The bottles are 25 years old, and I'm sure they weren't cleaned after they were emptied. I would like to use the bottles for new chemicals, but don't want to contaminate them with whatever chemical residue remains in the bottles. Is there a good way to clean them, or should I just buy new ones? Thanks, Noah

Which reasonably attainable chemical best attracts electrons? Answered

I'm building a secret project, but I need a chemical that can attract electrons. It has to be easily attainable, relatively cheap, and it can't easily hurt me. I think that my question, is (if possible), which safe chemical is the best at attracting electrons? If one wouldn't have a noticeable effect under those parameters, is there one that would be noticeable at all?

which chemical to deactivate microchips? Answered

Hi, I'm making a cryptex, such a thing like in the Da Vinci Code, and I'm going to make an Instructable of it later. But I'm going to hold USB-sticks in it instead of a piece of paper. That's a little more modern nowadays people lose a lot of usb sticks with secret important information so I'll use a cryptex for it. The crpytex like it was invented by Da Vinci contained a paper, which was rolled around a tube with vinegar in it. If someone decided to just smash the cryptex, the tube breaks and the vinegar would destroy the ink on the paper, making it unreadable. I don't think that works good in real but I don't think it will deactivate a usb stick either. So I want something else in the tube that DOES eat the chip. So I'll remove the outside wrapping of the USB-stick. What fluid can I use?

Is it possible to prevent the chemical reaction that occurs when a tin is boiled in an aluminium pot?

When a tin is boiled in an aluminium pot a chemical reaction takes place that creates a grey film in the pot. This can be removed with some very vigorous scrubbing with steel wool - it takes hours! Can the chemical reaction be prevented or is there another reaction that can be created that will remove the grey film?

Aluminum from aluminum hydroxide?

I have some aluminum hydroxide and I have been trying to find a way to strip the Al(OH)3 of it's hydroxide ions to form an aluminum precipitate. It's nonsoluble so a reaction in an aqueous solution does not seem to be an option, also considering that the only other more reactive metals than it would ignite upon contact with water anyhow. Does anyone have any ideas how to accomplish this?

Is there a relatively safe alternative to vinegar and baking soda for chemical reaction volcanoes? Answered

My brother is working on a paper mache volcano experiment for school, and I figured that the instructables community has come up with something a little more creative than just vinegar and baking soda. When I say relatively safe I mean something that doesn't emit poisonous gasses or toxic waste.  Thanks for any help. Update: I'm not worried about the safety of vinegar and baking soda, I added a safety request because I was almost very stupid mixing chemicals without checking about results. I almost created a gas used to exterminate people. There is no need to lecture me on how stupid this was, I already know.

PCB etching question?

I wanted to start making PCBs. However, I read that because the chemicals dissolve the copper, you can't dump it down the sink or throw it away because it is "hazardous" and should be taken to hazardous waste disposal. I'm still in high school and can't really do that and/or my parents would think I'm doing something dangerous. Is there any other way to etch PCBs besides using chemicals, like a knife or something?

what chemicals aside from bicarb soda are present in pool ph buffer? Answered

Hello i just went to the dump shop and picked up a 4kg bag of bicarb soda as ph buffer for free, and when i got home, i noticed it smelt of ammonia, so i though it might have some ammonium carbonate, so i figured i could get rid of it by adding some water to the ph buffer and then boiling it. however, i have noticed that it turned my hands blue, and although the blue washed off, i am now hazardous as to what else may be in thr ph buffer, although it states sodium bicarbonate is the active ingredient. i plan on dividing it, selling 2kg on my site in 250g batches for $2 each, and the other i plan to use as a sodium source for my sodium reduction cell. i need to know though, what the other chemicals in the pool buffer are so i can state the purity of the ph buffer. also will anything lebeled as "soda ash" be pure sodium carbonate?
