Solution 1992-1

(a) Addition of KCN
(b) Addition of excess of NaOH.
(c) Addition of excess of NH4OH.

Solution 1993-1

Solution 1995-1

(a) The metal ion present in solution A is Pb2+.
(b) The cation present in solution B is Cu2+. The probable colour of solution B is blue.

Solution 1996-1

Solution 1996-2

The solutions for the tests will be prepared by dissolving the given powders separately in water.
(i) Solution of Calcium carbonate:
Calcium carbonate is CaCO3 and contains Ca2+ ions. Sodium hydroxide solution NaOH can be used to identify Ca2+ since its addition to calcium carbonate solution will give white precipitates of Ca(OH)2 which are sparingly soluble in excess of NaOH.
(ii) Solution of Lead carbonate:
Lead carbonate is PbCO3 and contains Pb2+ ions. Ammonium hydroxide solution NH4OH can be used to identify Pb2+ since its addition to lead carbonate solution will give white precipitates of Pb(OH)2 which are insoluble in excess of NH4OH.
(iii) Solution of Zinc carbonate:
Zinc carbonate is ZnCO3 and contains Zn2+ ions. Sodium hydroxide solution NaOH can be used to identify Zn2+ since its addition to zinc carbonate solution will give white gelatinous precipitates of Zn(OH)2 which are soluble in excess of NaOH.

Solution 2013-1

(i) (a) When NH4OH is added to copper (II) nitrate solution in small quantities, a pale blue precipitate is observed.

 (b) When added in excess, NH4OH dissolves to give an inky blue solution forming a complex salt.

 

(ii) (a) When NH4OH is added to zinc nitrate solution in minimum quantity, it forms a gelatinous white precipitate.

 (b) When added in excess, it dissolves to form a complex salt.
