I thought the wash procedure would be similar. The precipation from AR and the gold powder from the cell both could contain similar contaminants (The cell of course could be dirtier) Therefore similar washes.
I followed Harolds advice-Hot HCL (boil) and the powder settled and I was able to decant and wash with water again.
What does the Amonia do that makes the powder become so fine that it remains suspended?
