Question about the sulfur cell

[zamistro]

Do I use straight sulfuric acid or am I supposed to have some gold alrady in solution?


I've been hearing conflicting things.

No gold in solution. Gold deplates from items as small paticals. Go to Lasersteves web site and look at his video's.

That's not how it works.

In the close proximity of the anode (the parts being stripped), current transforms sulfuric acid to persulfuric acid, which dissolves gold. As the dissolved gold migrates away from the anode, the current level required diminishes, which, in turn, causes the persulfuric acid to revert back to sulfuric acid, which is not capable of holding gold in solution, so it precipitates as miniscule particles.

Thanks Harold for correcting me on this.
