Lab Safety Guideline: Aqua Regia
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.

Aqua regia | Podcast | Chemistry World
Tabitha Watson. Way back in the 8 th century AD, an alchemist by the name of Jabir ibn Al-Hayyan prepared the first recorded batch of aqua regia, a mixture of nitric and hydrochloric acid in a 1:3 ratio. Named from the Latin for 'royal water', this volatile mixture turns from colourless to a fiery yellow-orange within a few seconds of being ...

How to Prepare Aqua Regia Acid Solution
Prepare Aqua Regia Solution. The usual molar ratio between concentrated hydrochloric acid and concentrated nitric acid is HCl:HNO 3 of 3:1. Keep in mind, concentrated HCl is about 35%, while concentrated HNO 3 is about 65%, so the volume ratio is usually 4 parts concentrated hydrochloric acid to 1 part concentrated nitric acid.
