Calcium Hydroxide - Ca(OH)2. Calcium hydroxide, commonly referred to as slaked lime, is described by the chemical formula Ca(OH)₂. It is an inorganic compound which has a white, powdery appearance in its solid-state.

Applications Across Multiple Industries

Calcium Hydroxide is highly valued in water treatment to neutralize acidity and remove impurities. In construction, it serves as a key component for soil stabilization and mortar preparation. Its chemical properties are also harnessed in the plastics and petroleum industries for process optimization and environmental management. Flue gas treatment further benefits from hydrated lime's reactivity with pollutants.

Safe Handling and Storage Recommendations

Despite being classified as non-hazardous by GHS, Calcium Hydroxide should be stored in airtight containers, away from moisture, in a cool and dry environment. Proper storage preserves its reactivity, prolongs shelf life to 12-24 months, and prevents clumping or degradation. Usage of gloves and protective equipment is advised during handling to avoid skin or eye irritation.
