Calcium hydroxide (chemical formula: Ca(OH)₂) is an inorganic compound formed by calcium ions (Ca²⁺) and hydroxide ions (OH⁻).
Key Properties:
Prepared by adding water to calcium oxide (slaking lime): highly exothermic.
Sparingly soluble in water; forms alkaline solutions (pH ~12.4).
Reacts with CO₂ to form calcium carbonate (used in mortar hardening).
Strong base: neutralizes acids, precipitates metals.
Major Uses:
Construction: Mortar, plaster.
Water Treatment: pH adjustment, impurity removal.
Food Industry: Pickling agent, corn processing (E526).
Agriculture: Soil acidity neutralizer ("lime").
Chemical Synthesis: Precursor for bleach, calcium salts.
Safety: Corrosive; requires protective gear. Rarely occurs naturally (mineral portlandite).
