A substance `(A)` is water insoluble On bubbling `Cl_(2)` through its suspension in water, it produces a coloured aqueous solution, forming a single product, `(A)` may be `:`

Options

A. `BiOCl`
B. `CuCl`
C. `Hg_(2)Cl_(2)`
D. All of these

Explanation

To solve the question, we need to identify the substance (A) that is water insoluble and reacts with chlorine gas (Cl₂) to produce a colored aqueous solution. Let's break down the solution step by step:

### Step 1: Analyze the properties of substance (A)
- The problem states that substance (A) is water insoluble. This means that (A) does not dissolve in water.

**Hint:** Look for substances that are known to be insoluble in water.

### Step 2: Consider the reaction with chlorine gas (Cl₂)
- When Cl₂ is bubbled through the suspension of (A) in water, it produces a colored aqueous solution. This indicates that (A) is likely a halide that can be oxidized by Cl₂.

**Hint:** Think about which insoluble halides can react with chlorine to form colored solutions.

### Step 3: Evaluate possible candidates for (A)
- The options provided include:
1. BiOCl (Bismuth oxychloride)
2. CuCl (Copper(I) chloride)
3. Hg₂Cl₂ (Mercury(I) chloride)

- **BiOCl**: This compound is not oxidized by Cl₂, so it cannot be the correct answer.
- **CuCl**: This compound can be oxidized by Cl₂ to form CuCl₂, which is a colored solution (copper(II) chloride is blue).
- **Hg₂Cl₂**: This compound can also be oxidized by Cl₂, but it does not produce a distinctly colored solution.

**Hint:** Focus on the oxidation reactions and the resulting products to determine the correct substance.

### Step 4: Determine the correct answer
- Since CuCl reacts with Cl₂ to form CuCl₂, which is a colored solution, the correct answer for substance (A) is **CuCl**.

### Final Answer:
Substance (A) may be **CuCl** (Copper(I) chloride).
