A
Aqua-regia
Aqua-regia is a highly corrosive mixture of nitric acid and hydrochloric acid in a 1:3 ratio. It is one of the few substances that can dissolve gold and platinum. The name 'aqua-regia' translates to 'royal water' in Latin, due to its ability to dissolve noble metals like gold. It is commonly used in the refining process of gold and in analytical chemistry.
