The correct Answer is:
To solve the matching question, we will analyze each item in Column I and find the corresponding item in Column II based on their chemical properties and tests. ### Step-by-Step Solution: 1. **Chromyl Chloride Test (A)**: - The chromyl chloride test is used to identify the presence of chloride ions (Cl⁻). When chloride ions are treated with potassium dichromate in an acidic medium, chromyl chloride (CrO₂Cl₂) is formed, which produces red fumes. - **Match**: (A) → (s) Cl⁻ 2. **Ring Test (B)**: - The ring test, also known as the brown ring test, is used to detect nitrate ions (NO₃⁻). In this test, a sample containing nitrate ions is treated with ferrous sulfate and dilute sulfuric acid, resulting in the formation of a brown complex that indicates the presence of nitrate ions. - **Match**: (B) → (q) NO₃⁻ 3. **Smell of Vinegar (C)**: - The smell of vinegar is characteristic of acetic acid (CH₃COOH), which has a distinct vinegar-like odor. The acetate ion (CH₃COO⁻) is also associated with this smell. - **Match**: (C) → (r) CH₃COO⁻ 4. **Smell of Rotten Eggs (D)**: - The smell of rotten eggs is associated with hydrogen sulfide (H₂S), which contains sulfide ions (S²⁻). The presence of these ions is responsible for the characteristic odor. - **Match**: (D) → (p) S²⁻ ### Final Matches: - (A) → (s) Cl⁻ - (B) → (q) NO₃⁻ - (C) → (r) CH₃COO⁻ - (D) → (p) S²⁻
