What do you see when.. i) Sodium hydroxide solution is added to zinc sulphate solution till it is in excess. ii) Chlorine water is exposed to sunlight. iii). Ammonia gas is bubbled through red litmus solution. iv). Barium chloride solution is added to dilute sulphuric acid. V.) Silver chloride exposed to sunlight​

Answer 1

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
