Salts M, N, O, P and Q undergo reactiom (i) to (v) respectively. Identify the cation present in these salts on the basis of these reaction. Tabulate your answer in the format given below. 1. When sodium hydroxide solution is added to the salt M, and heated strongly a colourless gas with a pungent smell is evolved which turm red litmus paper blue and gives dense white fumes with a moist glass rod with hydrochloric acid. 2. Addition of dilute hydrochloric acid to a solution of N gives a thick white precipitate which is soluble in hot water. 3. When ammonium hydroxide solution is added to the solution of 0 a light blue precipitate is obtained which is soluble in excess of ammonium hydroxide to form an inteme deep blue solution. 4. When ammonium hydroxide solution is added to the solution of P reddish brown (mustard colour) precipitate is obtained which ,is insoluble even in the excess of ammonium hydroxide solution. 5. When sodium hydroxide solution is added to the solution of Q a which coloured gelatinous precipitate is obtained which is soluble in excess of sodium hydroxide to form a clear solution
