CalciumOxide

Calcium Oxide lumps Extra Pure is a high-purity, white to grayish solid commonly known as quicklime, widely used in laboratory settings for its strong basic and dehydrating properties. In analytical and preparative chemistry, it is utilized for drying organic solvents and gases, preparing calcium hydroxide solutions, and studying exothermic hydration reactions. Its reactive nature with water makes it ideal for demonstrations of heat evolution and chemical changes. The lump form provides a slower, controlled reactivity, especially useful in large-scale or prolonged experiments. The extra pure grade ensures consistent composition with minimal impurities, essential for precise scientific applications. It must be stored in airtight containers to prevent reaction with atmospheric moisture and carbon dioxide.
