Potassium dicyanoaurate Wikipedia

Potassium dicyanoaurate is produced in the cyanide process variant of gold mining. The chemical reaction for the dissolution of gold, the "Elsner Equation", is: 4 Au + 8 KCN + O2 + 2 H2O → 4 K[Au(CN)2] + 4 KOHIn this redox process, oxygen removes, via a two-step reaction, one electron from each gold atom to form the complex Au(CN) 2 ion.

Solubility Product Purdue University

We then write the solubility product expression for this reaction. K sp = [Ag +][Br-] = 5.0 x 10-13. One equation can't be solved for two unknowns the Ag + and Br-ion concentrations. We can generate a second equation, however, by noting that one Ag + ion is released for every Br-ion. Because there is no other source of either ion in this solution, the concentrations of these ions at
