Details

Calcium Oxide Powder, Lab Grade

Calcium Oxide, also known as Quicklime, has the chemical formula CaO. It appears as a white powder, and is sparingly soluble in water, soluble in acids, and reacts with water to form calcium hydroxide (slaked lime), releasing significant heat.

Lab grade chemicals possess reasonable purity but do not comply with any official standard for quality or purity like the ACS Grade, the USP Grade, or the FCC Grade. The Lab Grade is also known as Laboratory Reagent (LR) and Chemically Pure (CP). Calcium Oxide, Lab Grade is recommended for educational institutes, research labs, and commercial applications.
