SMB as a reducing agent.

[youngleo]

Why is SMB used as a reducing agent for Auric Chloride (isn't it actually Chloroauric acid)? Why wouldn't we use another chemical that is cheaper? Is SMB more effective for some reason?



Also, does anybody know the chemical equation on this reaction between Chloroauric acid and SMB?

SMB creates SO2 gas when it get wet and this reacts with the solution to drop your gold in fine powder form.

Here's a post for common gold reactions:

I found this by searching for 'SO2 reaction pudding' at:

Pudding was included to narrow the search to only my posts as this word is in my signature line and hence all of my posts.

Pudding? Heck Steve, that's almost cheating.

It is a good technical tip for the rest of us that may have not been so sharp.

Yes, I see the SO2 gas posts now. It makes sense. Thanks for your help guys. It is very appreciated. Maybe after a few months on this forum I could try my hand at this. I just want to develop an understanding of the dangers and benefits before doing anything.

Wise indeed, I wish more took this approach. Even as a hobby it is a fun thing to do, but due diligence must be done if you wish to stay healthy as in one piece.
