Full Description
Sodium Carbonate (Na2CO3) is an inorganic salt that functions primarily as a pH adjustment agent across multiple industrial applications. This water-soluble compound serves critical roles in agriculture, food & beverage processing, HI&I cleaning, industrial manufacturing, mining, oil & gas, textiles, and water treatment operations. Available in both light and dense anhydrous forms, sodium carbonate decomposes at elevated temperatures through CO2 loss and exhibits high water solubility while remaining insoluble in ethanol.
