CaOHO

CaOHO is a chemical formula that represents calcium hydroxide. It is an inorganic compound with the formula Ca(OH)2. Calcium hydroxide is also known by several common names, including slaked lime, hydrated lime, or builder's lime. It is a white, powdery solid that is produced when calcium oxide (quicklime) is reacted with water in a process called slaking. This reaction is exothermic, meaning it releases heat.

Calcium hydroxide is sparingly soluble in water, forming a milky suspension called limewater when dissolved in sufficient quantity. The solution is alkaline due to the release of hydroxide ions. It is a widely used chemical with numerous applications. Historically, it has been used as a building material in mortar and plaster due to its ability to harden over time by reacting with atmospheric carbon dioxide to form calcium carbonate.

In industry, calcium hydroxide is employed in water treatment to adjust pH and soften water by precipitating magnesium and calcium ions. It is also used in the refining of sugar, in the manufacture of paper, and in the production of various chemicals. In agriculture, it is used as a soil conditioner to neutralize soil acidity. It also finds use in the food industry as a firming agent and in some food processing applications. Due to its alkaline nature, contact with calcium hydroxide can cause irritation to skin, eyes, and the respiratory tract.
