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, water treatment, and as a pH regulator in various industrial processes. In agriculture, Ca(OH)₂ serves as a soil amendment to reduce acidity and improve nutrient availability. It also plays a role in the food industry, where it is used in the preparation of certain foods, such as pickles and tortillas, enhancing texture and flavor.
