Sodium Carbonate

(a) Name the raw materials used in the manufacture of sodium carbonate by Solvay process. (b) How is sodium hydrogen carbonate formed during Solvay process separated from a mixture of NH_(4)Cland NaHCO_(3) ? (c ) How is sodium carbonate obtained from sodium hydrogen carbonate ?

Write the formulae of sodium chloride and sodium carbonate. Explain why an aqueous solution of sodium chloride is neutral but an aqueous solutio of sodium carbonate is basic (or alkaline). Write chemical equations of the reactions involved.
