Description and uses:

One of the strongest mineral acids known. Shows strong oxidising action towards many substances (including many metals) through reduction of the nitrate ion (NO3(-)) (N(V))to nitrous oxide (NO) (N(II)).

Dissolves many metals including copper, tin and silver.

Combined with hydrochloric acid it constitutes Aqua Regia, which due formation of nitrosyl chloride (NOCl) increases the oxidising power of nitric acid considerably. Mixtures (by volume) of 40 part HNO3 35 w% and 125 parts of HCl 37 w% for instance dissolve gold and other precious metals.
