The preferred salt is usually Sodium Nitrate. The chemistry behind AR is a bit more involved then you might expect, so we will just go over what is necessary for us to understand the process, in simple terms. In Aqua Regia, the Nitrate ions serves as an oxidizer where the Chloride ions act as sort of "receptors" and accommodate the oxidized metals.
