e. (A) gives chromyl chloride test .

Text Solution

AI Generated Solution

To identify the compound \( A \) based on the given facts, we will analyze each statement step by step. ### Step 1: Analyze the first statement **Statement:** \( A \) reduces \( HgCl_2 \) solution to a white precipitate changing to gray. **Explanation:** When \( A \) (which we suspect to be a tin compound) reacts with \( HgCl_2 \), it forms \( Hg_2Cl_2 \) (mercurous chloride), which is a white precipitate that can turn gray upon further reaction. This indicates that \( A \) is likely to be a reducing agent. ### Step 2: Analyze the second statement ...
