When slaked lime is treated with chlorine, the product obtained is
(a)`CaCl_2`
(b)`Ca(ClO)_2`
(c)`Ca(ClO_3)_2`
(d) `CaOCl_2`

Options

A. `CaCl_2`
B. `Ca(ClO)_2`
C. `Ca(ClO_3)_2`
D. `CaOCl_2`

Explanation

To solve the question of what product is obtained when slaked lime (calcium hydroxide, Ca(OH)₂) is treated with chlorine, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Slaked Lime**:
- Slaked lime is chemically represented as calcium hydroxide, which is \( \text{Ca(OH)}_2 \).

2. **Understand the Reaction**:
- When slaked lime is treated with chlorine gas (\( \text{Cl}_2 \)), a chemical reaction occurs.

3. **Write the Reaction**:
- The reaction can be represented as:
\[ \text{Ca(OH)}_2 + \text{Cl}_2 \rightarrow \text{Ca(OCl)}_2 + \text{H}_2\text{O} \]
- Here, chlorine reacts with calcium hydroxide, resulting in the formation of calcium hypochlorite (\( \text{Ca(OCl)}_2 \)) and water.

4. **Identify the Product**:
- The product formed from this reaction is calcium hypochlorite, which is commonly known as bleaching powder.

5. **Select the Correct Option**:
- Among the given options:
- (a) \( \text{CaCl}_2 \) - Calcium chloride
- (b) \( \text{Ca(ClO)}_2 \) - Calcium hypochlorite
- (c) \( \text{Ca(ClO}_3)_2 \) - Calcium chlorate
- (d) \( \text{CaOCl}_2 \) - Calcium hypochlorite (same as option b)
- The correct answer is (b) \( \text{Ca(ClO)}_2 \) or (d) \( \text{CaOCl}_2 \) since both represent calcium hypochlorite.

### Final Answer:
The product obtained when slaked lime is treated with chlorine is:
**(b) \( \text{Ca(ClO)}_2 \)** or **(d) \( \text{CaOCl}_2 \)**.
