1 Answer

Answer :

(1) conc. nitric acid and conc. hydrochloric acid Explanation: Aqua regia or nitro-hydrochloric acid is a highly corrosive mixture of acids, a fuming yellow or red solution. The mixture is formed by freshly mixing concentrated nitric acid and hydrochloric acid, usually in a volume ratio of 1:3. It was named so because it can dissolve the so-called royal or noble metals, gold and platinum. However, titanium, iriditim, ruthenium, tantalum, osmium, rhodium and a few other metals are capable of withstanding its corrosive properties.
