When potassium iodide solution is added to a solution of lead (II) nitrate in a test tube, a precipitate is formed. (a) What is the colour of this precipitate? Name the compound precipitated. (b) Write the balanced chemical equation for this rection. (c) List two types of reactions in which this reaction can be placed.

An aqueous solution containing S^(2-) ions will not give:

An aqueous solution containing S^(-2) ions will not give

When Al is added to sodium hydroxide solution:

Cu^(2+) ions give white precipitate with :

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

On reaction of sodium hydroxide with Iron(II) ion gives the coloured precipitate. Tell the colour .

From the solution containing copper (+2) and zinc (+2) ions copper can be selectively precipitate using sodium sulphide.
