Ca(OH)₂

Calcium hydroxide, or Ca(OH)₂, is a chemical compound made of calcium, oxygen, and hydrogen. It appears as a white, powdery substance and is commonly called lime or slaked lime. It’s used in various applications such as treating water to make it safe, adjusting pH levels in soil, and in the construction industry for making mortar and plaster. When dissolved in water, Ca(OH)₂ produces a alkaline solution that can neutralize acids. It is also important in food processing, like in the production of certain pickles and tortillas, owing to its chemical properties.
