Sodium carbonate, Na2CO3, is the inorganic compound with the formula Na2CO3 and its varioushydrates. All forms are white, water-soluble salts. All forms have a strongly alkaline taste and givemoderately alkaline solutions in water. sodium carbonate became known as "soda ash".Itis produced in large quantities from sodium chloride and limestone by the Solvay process. In terms of its largest applications, sodium carbonate is used in the manufacture of glass, paper, rayon, soaps,and detergents.
