Salts P, Q,R,S,T,U and V undergo reactions (i) to (vii) respectively. Identify the cation present in these salts on the basis of these reactions. Tabulate your answer in the formate given below. (i) When the salt Pis heated with sodium hydroxide solution a vigorous reaction takes place and a colourless gas is evolved with a pungent and suffocating smell that brings tears in our eyes. The evolved gas gives dense white fumes with a moist glass rod depped with hydrochloric acid. (ii) Addition of sodium hydroxide solution to a solution of salt Q gives a thick white precipitae which is soluble in excess of sodium hydroxide solution to form a clear solution. (iii) Addition of ammonium hydroxide solution to a solution of salt R gives a dark blue precipitate which is soluble is excess of ammonium hydroxide solution to form an intense deep blue solution. (iv) Addition of ammonium hydroxide solution to a solution of 5 gives a dirty green [bottle green] precipitate which is insoluble even in the excess of ammonium hydroxide solution. (v) Addition of ammonium hydroxide solution to a solution of T gives a reddish brown (rust precipitate] precipitate which is insoluble even in the excess of ammonium hydroxide solution. (vi) Addition of ammonium hydroxide solution to a solution of V gives a geletaneous white precipitate which is soluble in excess of ammonium hydroxide solution to form a clear solution. (vii) Addition of ammonium hydroxide solution to a solution of V gives no precipitate but it gives a chalky white precipitate with sodium hydroxide solution which is insoluble even in the excess of sodium hydroxide solution.

Tabulate your answer in the format given below: (i) Addition of potassium chromate solution to a solution of salt K gives a golden yellow precipitate. (ii) Addition of potassium ferrocyanide solution to a solution of slat L gives a chocolate brown precipitate. (iii) Addition of potassium ferricyanide solution to a solution of salt M gives an intese deep blue solution. (iv) Addition of potassium ferrocyanide solution to a solution of O gives a bluish white precipitate.

A white sodium salt dissolves in water to give a solution which is neutral to litmus.When silver nitrate solution is added to the solution, a white precipitate is obtained which does not dissolve in dilute HNO_(3) .The anion is

Salts A, B, C, D and E undergo reactions (i) to (v) respectively. Identify the anion present in these salts on the basis of these reactions. Tabulate your answers in the format given below: (i) When silver nitrate solution is added to a solution of A, a white precipitate, insoluble in dilute nitric acid, is formed. (ii) Addition of dilute hydrochloric acid to B produces a gas which turns lead acetate paper black. (iii) When a freshly prepared solution of ferrous sulphate is added to a solution of C and concentrated sulphuric acid is gently poured from the side of the test-tube, a brown ring is formed. (iv) When dilute sulphuric acid is added to D a gas is produced which turns acidified potassium dichromate solution from orange to green. (v) Addition of dilute hydrochloric acid to E produces an effervescence. The gas produced turns lime water milky but does not affect acidified potassium dichromate solution.

The salt which in solution gives a pale green precipitate with sodium hydroxide solution and a white precipitate with barium chloride solution is
