Question on AP Process

[chemist]

I have been looking around, but I can't find the answer to this question:
How much AP (HCl and peroxide) is needed to dissolve an ounce of metal?

For the technical folks, the HCl is 35% and the metal is copper.
The AP will be 2:1.

You can read the Copper Chloride document on my website to get an idea as too how much copper AP will absorb. It depends on a lot of factors which will vary for each reaction.

The referenced document will explain the chemistry involved.

The solution will continue to absorb copper as long as it does not become too basic or too saturated with copper I chloride.

Wow, that was a great explanation of the process. Now I understand a bit more about how AP etches base metals. I used to etch printed circuit boards with ferric chloride solution (from Radio Shack). This is really the same type of reaction.
Thanks a ton!
