How many compounds are neutral ? `H_(2)O` , NaOH , HCL ,Nacl

Explanation

To determine how many compounds from the list are neutral, we need to analyze each compound based on its acidic or basic nature.

### Step-by-Step Solution:

1. **Identify the Compounds**: The compounds given are:
- H₂O (water)
- NaOH (sodium hydroxide)
- HCl (hydrochloric acid)
- NaCl (sodium chloride)

2. **Analyze H₂O (Water)**:
- Water is a neutral compound. It has a pH of 7, which indicates that it is neither acidic nor basic.
- **Conclusion**: H₂O is neutral.

3. **Analyze NaOH (Sodium Hydroxide)**:
- NaOH is a strong base. It dissociates in water to produce hydroxide ions (OH⁻), making the solution basic.
- **Conclusion**: NaOH is not neutral; it is basic.

4. **Analyze HCl (Hydrochloric Acid)**:
- HCl is a strong acid. It dissociates in water to produce hydrogen ions (H⁺), making the solution acidic.
- **Conclusion**: HCl is not neutral; it is acidic.

5. **Analyze NaCl (Sodium Chloride)**:
- NaCl is formed from the reaction of a strong acid (HCl) and a strong base (NaOH). The resulting solution of NaCl in water is neutral because it does not affect the pH.
- **Conclusion**: NaCl is neutral.

6. **Count the Neutral Compounds**:
- From the analysis, the neutral compounds are H₂O and NaCl.
- Therefore, the total number of neutral compounds is 2.

### Final Answer:
There are **2 neutral compounds**: H₂O and NaCl.
