Which sulphide is insoluble in dilute acids but soluble in alkalies:

A compound (A) is used in paints instead of salts of lead.Compound(A) is obtained when a white compound (B) is strongly heated . Compound (B) is insoluble in water but dissolves in sodium hydroxide forming a solution of compound (C ) the compounds (A) on heating with coke gives a metal (D) and a gas (E) which burns with blue flame . (B) also dissolves in ammonium sulphate solution mixed with ammonium hydroxide. solution of compound (A) in dilute HCl gives a bluish white//white precipitate (F) with excess of (F) with excees of K_(4)[Fe(CN)_(6)] identify (A) to (F) and explain the reactions.

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
