Which of the following salt is basic?

Options

A. `HOCI`
B. `NaOCI`
C. `NaHSO_(4)`
D. `NH_(4)NO_(3)`

Explanation

To determine which of the following salts is basic, we need to analyze the nature of each salt in terms of the acids and bases from which they are derived. A basic salt is typically formed from a strong base and a weak acid.

Let's go through the options step by step:

1. **Identify the salts and their components:**
- **HOCl**: This is not a salt; it is a weak acid (hypochlorous acid).
- **NaOCl**: This is the salt formed from the strong base NaOH (sodium hydroxide) and the weak acid HOCl (hypochlorous acid).
- **NaHSO4**: This salt is formed from NaOH (strong base) and HSO4^- (bisulfate ion, which is derived from sulfuric acid, a strong acid).
- **NH4NO3**: This salt is derived from NH4OH (ammonium hydroxide, a weak base) and HNO3 (nitric acid, a strong acid).

2. **Analyze each salt:**
- **NaOCl**: Since it is derived from a strong base (NaOH) and a weak acid (HOCl), it will be basic in nature.
- **NaHSO4**: This salt is derived from a strong base (NaOH) and a strong acid (HSO4^-), which does not make it basic.
- **NH4NO3**: This salt is formed from a weak base (NH4OH) and a strong acid (HNO3), indicating it will be acidic.

3. **Conclusion**:
The only salt that is basic is **NaOCl**.

### Final Answer:
The basic salt among the given options is **NaOCl**.
