Calcium hydroxide, represented by the chemical formula Ca(OH)2, is an inorganic compound commonly known as slaked lime or hydrated lime. It is a white, odorless powder that is highly soluble in water, forming a strong alkaline solution. This compound is often used in construction, agriculture, and water treatment due to its ability to neutralize acids and improve soil quality. In addition to its industrial applications, Ca(OH)2 plays a role in food processing, particularly in the preparation of certain foods like pickles and tortillas. It is also used in the production of calcium carbonate and as a pH regulator in various chemical processes.
