Write a balanced chemical equation with state symbols for the following chemical reactions:
(i) Solution of barium chloride and sodium sulphate in water to give insoluble barium sulphate and the solution of sodium chloride.
(ii) Sodium hydroxide solution (in water) react with hydrochloric acid solution (in water) to produce sodium chloride and water.
(i) BaCl2 (aq) + Na2SO4 (aq) –––> BaSO4 (s) + 2NaCl (aq)
(ii) NaOH (aq) + HCl (aq) –––> NaCl (aq) + H2O (liq)
