The acid test is a chemical test used to identify minerals. The test involves reacting a mineral with an acid, such as hydrochloric or nitric acid. If the mineral reacts with the acid, it is said to be acid-soluble. Acid-soluble minerals typically contain carbonate or sulfide minerals. If the mineral does not react with the acid, it is said to be acid-insoluble. Acid-insoluble minerals typically contain oxide or silicate minerals. The acid test is a simple and inexpensive way to identify minerals, and it can be used to distinguish between different types of minerals.
