Due to the reaction between its components resulting in its decomposition, aqua regia quickly loses its effectiveness (yet remains a strong acid), so its components are usually only mixed immediately before use. Upon mixing of concentrated hydrochloric acid and concentrated nitric acid, chemical reactions occur.

Aqua Regia solution is very energetic and potentially explosive. It is also very likely to become hot - more than 100°C. Handle with care. • Aqua Regia will melt some plastics and corrode most metals. • Never put Aqua Regia in a closed vessel; evolved gases will cause a pressure build-up and possible over-pressurization of your container.

In this research, a recycling process for palladium using "dry aqua regia," which consists of iron (III) chloride–potassium chloride, was proposed. Palladium was dissolved in "dry aqua regia," and the dissolved palladium was recovered by leaching with potassium chloride solution with added ammonium chloride and nitric acid.
