The following reactions have been given for the dissolution of gold in dilute cyanide solutions: 4Au + 8 NaCN + 02 + 2 H20 = 4 NaAu(CN) 2 + 4NaOH. This is known as Eisner's equation. 2Au + 4 NaCN + 2 H20 = 2NaAu(CN)2 + 2 NaOH + H2. This was suggested by Janin. 2Au + 4 NaCN + 2 H20 + 02 = 2 NaAu (CN)2 -f- 2 NaOH -f- H202.
