Question

Uses of aquaregia in chemistry

Answer 1

Answer:

Aqua regia is a very strong acid formed by the combination of concentrated nitric acid and concentrated hydrochloric acid, both of which are strong acids. It is generally used to remove metals like gold and platinum from substances, especially in microelectronics and micro-fabrications labs.

Explanation:

• Since aqua regia is just a mixture of two strong acids, it doesn’t have a chemical formula of its own. However, it can be represented as HNO3+3 HCl, which basically indicates that it’s a mixture of nitric acid (HNO-3) and hydrochloric acid (HCl).

Answer 2

Answer:

Aqua regia is a corrosive reagent used to clean glassware and in gold refining processes. It is made by mixing nitric acid and hydrochloric acid in a 1:3 ratio. The name comes from the Latin 'royal water', as it can dissolve gold and platinum - medals associated with royalty.
