What is the chemical formula of aqua-regia?

Answer 1

A mixture (acid) of HCl and HNO3. Formed by mixing 3 moles of HCl and 1 mole of HNO3 i.e in the ratio 3:1. This is one of the few acids that can dissolve metals like gold and platinum. FIrst discovered by the famous Muslim scientist Jabir-bin-Haiyan(known as the father of chemistry). It is a highly-corrosive fuming yellow liquid. The name "Aqua Regia" is latin for "Royal Water". It was so named because it could dissolve the royal noble metals.Aqua regia works to dissolve gold, even though neither constituent acid will do so alone because, in combination, each acid performs a different task. Nitric acid is a powerful oxidizer, which will actually dissolve a tiny (virtually undetectable) amount of gold, forming gold ions. The hydrochloric acid provides a ready supply of chloride ions, which react with the latter, thus taking the gold out of the solution. This allows further oxidation of gold to take place, and so the gold is dissolved.

Answer 2

Aqua Regia is a mixture of concerntraed hydrochloric acid(HCl) and concerntrated nitric acid(NH3) which is in the ratio of 3:1. It can dissolve gold, which single acids alone cannot do.

Answer 3

The chemical formula of aqua-regia is 3HCl (conc.) + HNO3 (conc.)

Answer 4

Aqua regia is a highly concentrated mixture of hydrochloric acid and nitric acid. It can react with metals such as gold and platinum that don't normally react with acid.

Answer 5

It is a chemical composed of Nitric and Hydrochloric acid that has the property to dissolve gold, platinum and palladium.

Answer 6

The chemical formula of aqua regia is HNO3 (nitric acid) and HCl (hydrochloric acid). It is a highly corrosive mixture used for dissolving noble metals like gold and platinum.
