A mixture of concentrated nitric and hydrochloric acids. It is a highly corrosive liquid able to attack gold and other resistant substances (in short, its strong!! ;) )

Hi !

Aqua regia is a mixture of two concentrated acids .
The acids , Hydrochloric acid (HCl) and Nitric acid (HNO₃) are mixed together in the ratio 3:1 , to get this solution.

3 parts of HCl , and 1 part of HNO₃

HCl or HNO₃ alone cannot dissolve  metals like gold .
But mixture of the concentrated solutions of these two acids ,in the ratio 3:1 , , can dissolve gold !

I have attached a picture of a gold being dipped into the aqua regia solution.
Refer to it !

Thanks !
