This “royal water” is a mixture of not one, but two acids – one part nitric acid to three parts hydrochloric acid. The nitric acid is able to prise a few gold atoms from the surface of the metal so the hydrochloric acid can strike and trap them in solution as AuCl4- (chloroauride ions). This gradual trickle of gold atoms into solution is not a rapid process, but for de Hevesy it must have been agonisingly slow.
