CaOH
Calcium hydroxide, commonly written Ca(OH)2, is a white, caustic, alkaline solid used widely in industry and agriculture. The shorthand CaOH is sometimes encountered, but the conventional chemical formula is Ca(OH)2.
Production and natural occurrence
Calcium hydroxide is produced by hydrating calcium oxide (quicklime): CaO + H2O → Ca(OH)2. This exothermic reaction yields
Calcium hydroxide is sparingly soluble in water. At 20–25°C its solubility is about 1.7 g per liter,
In agriculture, Ca(OH)2 is used to neutralize acidic soils and supply calcium for plant growth. In construction,
Calcium hydroxide is caustic and can cause irritation or chemical burns upon contact with skin or eyes.
Store in a dry, tightly closed container to prevent moisture uptake and carbonation.
