Identify the anion present in each of the following compounds - A, B, C: i] Salt'A' reacts with conc. H_2SO_4 producing a gas which fumes in moist air & gives dense fumes with ammonia. ii] Salt 'B' reacts with dil. H_2SO_4 producing a gas which turns lime water milky but has no effect on acidified potassium dichromate solution. iii] When barium chloride soln. is added to salt soln. 'C' a white precipitate insoluble in dil. HCl is obtained.

Identify the anion present in each of the following compounds : A salt D on treatment with dilute sulphuric acid produces a gas which turns lime water milky but has no effect on acidified potassium dichromate solution.

Identify the anion present in the following compound: Compound X on heating with copper turnings and concentrated sulphuric acid liberates a reddish brown gas.

Identify the anion present in the following compounds : Compound Z which on reacting with dilute sulphuric acid liberates a gas which turns lime water milky, but the gas has no effect on acidified potassium dichromate solution.

Name the gas evolved in each of the following cases : Addition of concentrated sulphuric acid to sodium chloride.

Give reason for each of the following: Copper sulphate pentahydrate turns white when treated with concentrated sulphuric acid.

Name the anion in each of the following compounds : Compound 'Z' on heating with conc. sulphuric acid, liberates a gas which on bubbling through silver nitrate solution gives a white precipitate, soluble in liquid ammonia.

Name the anion in each of the following compounds : Compound 'Y' on heating with dilute sulphuric acid, liberates a gas which turns lime water milky, but has no effect on potassium permanganate solution.

Identify the anion present in the following compounds: i] Compound X on heating with copper turnings & conc. sulphuric acid liberates a reddish brown gas. ii] When a solution of compound Y is treated with silver nitrate solution a white precipitate is obtained which is soluble in excess of ammonium hydroxide solution. iii] Compound Z which on reacting with dilute sulphuric acid liberates a gas which turns lime water milky, but the gas has no effect on acidified potassium dichromate solution. iv] Compound L on reacting with barium chloride solution gives a white precipitate insoluble in dilute hydrochloric acid or dilute nitric acid.
