Dàcid

Dàcid is a term derived from the Catalan language, meaning "acid" in English. It refers to a substance that has a pH value less than 7, indicating that it is acidic. Acids are characterized by their ability to donate hydrogen ions (H+) in a solution, which makes them corrosive and capable of reacting with metals and other substances. Common examples of dàcid include hydrochloric acid (HCl), sulfuric acid (H2SO4), and acetic acid (CH3COOH). These acids are widely used in various industries, including manufacturing, cleaning, and chemical production. However, they must be handled with care due to their corrosive nature and potential hazards to health and the environment. Proper safety measures, such as the use of protective equipment and proper disposal methods, are essential when working with dàcid substances.
