Elsner's equation
In dissolution of gold by dilute aerated cyanide solution this reads: 4Au + 8NaCN + O2+ 2H2O = 4NaAU(CN)2+4NaOH . Analogous equation is given for silver. Other mechanisms have been suggested by Janin and Bodlaender, the latter requiring two stages of reaction with the intermediate formation of hydrogen peroxide.
