About Calcium Oxide Powder, ACS Reagent Grade

Burnt lime, commonly known as calcium oxide (CaO), is a frequently used chemical substance. It is a white, caustic, alkaline, and crystalline solid at ambient temperature. Lime refers to calcium- containing inorganic compounds made up of calcium carbonates, oxides, and hydroxides, as well as silicon, magnesium, aluminum, and iron. Quicklime, on the other hand, refers to calcium oxide as a single chemical component. Chemicals in the Reagent Grade have a high purity and are best utilized for analytical purposes. They're useful in research investigations since they produce consistent, trustworthy, and repeatable findings.
