Thermodynamic study of gold chlorination leaching reactions. The standard electrode potential of the gold is as follows: (1) Au + + e = Au; E 0 = 1.691 V (2) Au 3 + + 3 e = Au; E 0 = 1.498 V. Gold is a metal with a high electrode potential and a low activity and exists mainly in a natural gold state in nature.
