Homonym: Acid Tests (Psychedelic)
An "Acid Test" is a simple chemical procedure used to identify the presence of certain substances, particularly minerals. In geology, it often refers to the reaction of calcium carbonate with hydrochloric acid, which produces carbon dioxide gas, causing fizzing or bubbling. This reaction helps geologists determine if a rock contains limestone or other carbonate minerals.
In a broader context, the term "acid test" can also refer to a definitive trial or evaluation of something's effectiveness or quality. For example, in business, an acid test might assess a company's financial health by examining its ability to meet short-term obligations without relying on inventory sales.
