(i) Salt 'A' reacts with conc. H2SO4 producing a gas which fumes in moist air and gives dense fumes with ammonia.
(ii) Salt 'B' reacts with dil. H2SO4 producing a gas which turns lime water milky but has no effect on acidified potassium dichromate solution.
(iii) When barium chloride solution is added to salt solution. 'C' a white precipitate insoluble in dilute hydrochloric acid is obtained.
