Bleaching powder is

Options

A. Double salt
B. Complex salt
C. Mixed salt
D. Normal salt

Answer

**Step-by-Step Solution:**

1. **Identify the Chemical Formula of Bleaching Powder:**
- The chemical formula for bleaching powder is \( \text{Ca(OCl)}_2 \).

2. **Determine the Components of Bleaching Powder:**
- Bleaching powder consists of one cation, which is calcium \( \text{Ca}^{2+} \), and two anions, which are \( \text{OCl}^- \) (hypochlorite ions).

3. **Classify the Type of Salt:**
- To classify bleaching powder, we need to understand the definitions of different types of salts:
- **Double Salt:** A combination of two different salts that crystallize together.
- **Complex Salt:** Contains a central metal atom bonded to ligands through coordinate bonds.
- **Mixed Salt:** Contains two different cations and/or two different anions.
- **Normal Salt:** Formed from the neutralization of an acid by a base.

4. **Analyze the Structure of Bleaching Powder:**
- Bleaching powder has one metal ion (calcium) and two anionic parts (two hypochlorite ions). This indicates that it does not fit the definition of a double salt since it does not consist of two complete salts.

5. **Evaluate Other Classifications:**
- It does not qualify as a complex salt because there are no coordinate bonds present in its structure.
- It cannot be classified as a normal salt because it has more than one anionic part.
- Since it contains one cation and two anions, it fits the definition of a mixed salt.

6. **Conclusion:**
- Therefore, bleaching powder is classified as a mixed salt.

**Final Answer:**
Bleaching powder is a mixed salt.
