I have been trying to find sulfamic acid to neutralise excess nitric in AR solution. Does it need to be pure sulfamic acid? There are many products containing 30-50% of it but i can't find 100% stuff.
I found possibly interesting product with sulfamic acid, SMB and a bit of tencides. It is used in farms, to wash milk tanks. Wondering, if it would be ready mixture to drop off gold from AR solution?
