Sodium Carbonate, Anhydrous, Granular, Reagent, ACS
Sodium Carbonate, Anhydrous, Granular, Reagent, ACS, commonly known as washing soda, is a vital component in various industrial and scientific applications. This fine, white powder is odorless and highly hygroscopic, effectively absorbing moisture from the air. Its primary application lies in glass production, where it serves as a flux for silica, significantly lowering the melting point and streamlining the glass-making process. Additionally, this sodium salt functions excellently as an electrolyte in chemical reactions, thereby enhancing its versatility within laboratory settings.
