Practice questions
Q1Aqua regia is a freshly prepared mixture of concentrated HNO3 and concentrated HCl in the ratio of __________ respectively.
Explanation
Aqua regia is prepared by mixing concentrated nitric acid and concentrated hydrochloric acid in the respective volume ratio of 1 : 3. This mixture is highly corrosive and can dissolve noble metals such as gold and platinum. The ratio 2 : 3 is not the standard composition used for aqua regia. The ratio 3 : 1 reverses the required acid proportion and would give excess nitric acid. The ratio 3 : 2 also does not match the accepted preparation of aqua regia.
