Answer: (i) 2NaOH + ZnSO4 -------> Na2SO4 + Zn(OH)2
(ii)When chlorine water is exposed to sunlight, it losses its yellow colour. It forms odourless gas called Oxygen.
(iii)The solution usually turns blue because NH3 gas is basic. It dissolves into aqueous solution and forms the NH4+ ion.
(iv) H2SO4 + BaCl2 -------> BaSO4 + 2HCl
