Calcium hydroxide, often referred to as slaked lime or hydrated lime, is a chemical compound with the chemical formula Ca(OH)₂. It is a white, crystalline solid with low solubility in water.
Description: Calcium hydroxide is produced by mixing calcium oxide (quicklime) with water in a process called slaking. The resulting product is a soft, white powder. In various industries, calcium hydroxide finds application due to its alkaline properties. In the construction industry, it is used in the preparation of lime mortar and plaster, contributing to their workability and durability. In agriculture, it is employed to neutralize acidic soils, promoting better plant growth. Calcium hydroxide is also utilized in water and wastewater treatment processes to adjust pH levels and precipitate impurities. Additionally, it plays a role in food production, particularly in the processing of pickles and certain fruits.
Safety Considerations: While calcium hydroxide is generally considered safe, direct skin contact should be avoided, and appropriate protective measures should be taken during handling.
Usage Guidelines: The usage of calcium hydroxide varies depending on the intended application. In construction and agriculture, it is applied in specific proportions to achieve desired results. For water treatment, the dosage is determined based on the water quality parameters and treatment goals. Manufacturers should follow recommended guidelines for safe and effective utilization.
