The correct Answer is:
To determine how many of the given cations belong to groups IIA, III, IV, and V in qualitative salt analysis, we will categorize each cation based on the standard classification of cations in qualitative analysis. ### Step-by-Step Solution: 1. **List the Cations**: The cations provided are: - Sr²⁺ (Strontium) - Hg₂²⁺ (Mercury(I)) - Pb²⁺ (Lead) - Zn²⁺ (Zinc) - Cu²⁺ (Copper) - Cr³⁺ (Chromium) - Ag⁺ (Silver) - Mg²⁺ (Magnesium) - Sb³⁺ (Antimony) 2. **Identify Group Classifications**: - **Group IIA (2nd Group)**: - Cations include: Sr²⁺, Mg²⁺, and Ba²⁺. - **Group III (3rd Group)**: - Cations include: Cr³⁺, Al³⁺, and Fe³⁺. - **Group IV (4th Group)**: - Cations include: Zn²⁺, Mn²⁺, and Ni²⁺. - **Group V (5th Group)**: - Cations include: Ba²⁺, Sr²⁺, and Ca²⁺. 3. **Categorize Each Cation**: - **Sr²⁺**: Belongs to Group V. - **Hg₂²⁺**: Belongs to Group I (1st Group). - **Pb²⁺**: Belongs to Group I (1st Group). - **Zn²⁺**: Belongs to Group IV. - **Cu²⁺**: Belongs to Group II (2nd Group). - **Cr³⁺**: Belongs to Group III. - **Ag⁺**: Belongs to Group I (1st Group). - **Mg²⁺**: Belongs to Group VI (6th Group). - **Sb³⁺**: Belongs to Group II B (2nd B Group). 4. **Count the Cations in Each Group**: - **Group IIA**: 1 (Sr²⁺) - **Group III**: 1 (Cr³⁺) - **Group IV**: 1 (Zn²⁺) - **Group V**: 1 (Sr²⁺) ### Summary of Results: - **Group IIA**: 1 (Sr²⁺) - **Group III**: 1 (Cr³⁺) - **Group IV**: 1 (Zn²⁺) - **Group V**: 1 (Sr²⁺) ### Final Answer: - **Cations belonging to Group IIA**: 1 (Sr²⁺) - **Cations belonging to Group III**: 1 (Cr³⁺) - **Cations belonging to Group IV**: 1 (Zn²⁺) - **Cations belonging to Group V**: 1 (Sr²⁺)
