Information

Sodium carbonate (Na2CO3), also soda or washing soda, is an inorganic compound. Is a sodium salt of carbonic acid. In terms of anhydrous white powder melting at 851 ° C. In water it is readily soluble to release the heat of hydration. Crystallization at room temperature can be the most important hydrate called. crystal soda (Na2CO3 · 10H2O). Aqueous solutions are strongly alkaline soda due to hydrolytic cleavage (it is a salt of a strong base and a weak acid). Soda is synthetically produced in large quantities of sodium chloride Solvay process.
