Question

Match List I with List II:

Choose the correct answer from the options given below:

• A. A-III, B-IV, C-II, D-I
• B. A-III, B-II, C-IV, D-I
• C. A-III, B-IV, C-I, D-II
• D. A-III, B-IV, C-II, D-I

Hint:

In qualitative analysis, cations are grouped based on their reactions with various reagents. Groups are determined by the solubility of the formed precipitates and their subsequent reactions.

Answer 1

The Correct Option is B

In cation analysis, the ions are grouped based on their behavior with specific reagents: - A. Co\(^2+\) (Cobalt): This ion is typically found in Group-III in cation analysis. So, A-III.
- B. Mg\(^2+\) (Magnesium): This ion is found in Group-II as it does not form precipitates with most reagents used for Group-I and Group-III cations. So, B-II.
- C. Pb\(^2+\) (Lead): This ion is typically found in Group-IV of cation analysis, as it forms precipitates with specific reagents used in this group. So, C-IV.
- D. Al\(^3+\) (Aluminum): This ion is found in Group-I. It is typically analyzed in Group-I due to its distinct behavior in reactions with different reagents. So, D-I.

Thus, the correct matching is (2) A-III, B-II, C-IV, D-I.
