Bleaching powder does not contain:

Options

A. `CaCl_(2)`
B. `Ca(OH)_(2)`
C. `Ca(OCl)_(2)`
D. `Ca(ClO_(3))_(2)`

Answer

To determine which compound does not contain bleaching powder, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Composition of Bleaching Powder**:
- Bleaching powder is primarily composed of calcium hypochlorite (Ca(OCl)₂), calcium chloride (CaCl₂), and calcium hydroxide (Ca(OH)₂).

2. **List the Given Compounds**:
- We need to analyze the four compounds provided in the question. Let's denote them as:
- A: Calcium hypochlorite (Ca(OCl)₂)
- B: Calcium chloride (CaCl₂)
- C: Calcium hydroxide (Ca(OH)₂)
- D: Calcium chlorate (Ca(ClO₃)₂)

3. **Compare Each Compound with the Composition of Bleaching Powder**:
- **Calcium hypochlorite (A)**: Present in bleaching powder.
- **Calcium chloride (B)**: Present in bleaching powder.
- **Calcium hydroxide (C)**: Present in bleaching powder.
- **Calcium chlorate (D)**: Not present in bleaching powder.

4. **Conclusion**:
- The compound that does not belong to the composition of bleaching powder is calcium chlorate (Ca(ClO₃)₂).

### Final Answer:
The compound that does not contain bleaching powder is **Calcium chlorate (Ca(ClO₃)₂)**.
