✦ Synopsis

The kinetics of the reaction between nitrous acid and gold(Ill) in an HCI medium was studied. The reaction was first order with respect to rAu III] and [HNO2]'H + and C1-ions inhibit the rate and alkali metal ions have specific effects on the rate. The reaction appears to involve different gold(III) species, viz. AuC1Z, AuC13(OH2) and AuC13(OH)-, which undergo a two-equivalent reduction to gold(I) leading to the formation of NO~-which undergoes rapid hydrolysis to give nitric acid.
