Okay a question for the DU science genius' out there...

[Javaman]

is there a type of acid that has copper as a base or a type of acid that has copper as a component?

I'm not chemistry student nor do I play one on TV so please be gentle if my question is outrageously ignorant.

1. OUTRAGE!OUTRAGE! IGNORANCE!OUTRAGE!

Nah - I got no idea. Just got outta gdp.

:P

2. cupric acid

I know no more!

google is your friend

5. Thanks! nt

3. Cupric Chloride

CuCl2

Now you know as much as I do. :D

[Javaman]

4. Thanks! nt

7. It's great if you want to etch some circuit boards

Which is what I used it for.

8. Cupric Chloride Is A Salt

That's not an acid in the traditional sense. A Lewis acid is an electron acceptor, but doesn't necessarily have other Bronsted acid qualities. IOW, if you poured it on your hands, you wouldn't get burned.

It's a very weak Lewis acid, and is nearly neutral pH. It reacts with stronger alkali substances to copper oxides and a stronger cationic salt. (Like if you react it with lye, it would give you potassium chloride and cupric hydroxide.)

It can be reacted with weak bases (like triethanolamine) to create a stable catalyst for transisomerizations. For instance, that's how they get neoprene!

Just thought i'd add more clarity than what in the Wiki entry.

11. I'm gonna alert on you if you post any more about frickin'

Lewis acids and electron acceptors on DU. I fled this crap by declining to take PChem for a Chem minor back in college and you have to drag it up and pollute DU with it????????

My eyes!!!!! My eyes!!!!! ARGHHHH!!!!!!

:evilgrin:

The C I got in Inorganic Chem was the hardest thing I ever worked for, except for MAYBE the freshman vet school autonomic nervous system section...........

14. Thanks Prof, that gives me exactly the info I was looking for. :) cheers! nt

16. My chemistry is really weak

Thanks for the clarification. Like I said above, I remember using cupric chloride to etch circuit boards but on I just did some googling and it seems like that was cupric chloride in a hydrochloric acid solution. The stuff I used before that was ferric chloride solution.

6. whatch makin' there, man?

13. I'm just doing some research on a chem spill from back in the 1970's. nt

9. Cuprous Thiocyanate is a strong one

It's actually the salt (ionic combination) of thiocyanic acid.

Here's a gloss page:

http://chemicalland21.com/industrialchem/organic/CUPROUS%20THIOCYANATE.htm

Generically, there are a lot of "cuprous acids." A number of them are used by living organisms, especially plants. Cuprous acids are also useful substances in industry. One modern application involves the manufacture of circuit boards.

10. Read My Reply To Another Poster

It's not an acid in the traditional sense. It's nearly pH neutral in water. It has some properites of acids, but in the Lewis sense, not the Bronsted sense. It doesn't donate protons, but will accept electrons.

It seems like a small distinction, but not to a chemist.

12. Trade ya, my SO's father dumbs a mixture of bleach and ammonia

on his cement floor in his basement, then can't understand why everyone in the house has burning eyes, nostrils and sever head aches as well as short tempers from the head aches. By mixture I mean he pours a half gallon of bleach on the floor then a whole 16oz bottle of ammonia. Yes I have told him time after time do not do that, but he sneaks down stairs and does it and you don't know it until the fumes hit up stairs, then its to late. I keep dumping both but he sneaks out and buys more.

[Javaman]

15. Why in gods name is he doing that? heck, I'm no chemist but even I

know one doesn't do that!

isn't that the basics for mustard gas?

[Sal Minella]

17. It's the basis for something nasty -- I accidentally did that once and it dissolved the plastic

brush I was using and made such a gawdawful smell I fled the house.

18. This makes chloramine, dichloramine, and nitrogen trichloride (explosive).

Google chloramine to see why you shouldn't be breathing that stuff. It's nearly as bad as breathing chlorine.

[angstlessk]

20. I believe it IS explosive .. a woman put both in the laundry and the washing machine

blew up. I do not recall if anyone was injured or killed, just that the combination, besides killing you with the fumes can also kill you with an explosion!!!

[eppur_se_muova]

21. Yep. Depends on how much of each you use, temperature, etc.

Can also make small amounts of hydrazine, which is rocket fuel, and toxic.

DON'T mix those chemicals at home, folks! Most bleach and ammonia bottles have labels warning against exactly that!

[eppur_se_muova]

19. Hmmm ... got a use/quote in context?

There are compounds known as "cuprates" but there really isn't a corresponding "cupric acid". Google gives so few hits I'm inclined to believe it's only locating misusage of the terminology.
