Select the odd one out and justify your choice:
`HCl,NaCl,HNO_(3),CH_(3)COOH`

Explanation

To solve the question of selecting the odd one out from the list of substances: HCl, NaCl, HNO3, and CH3COOH, we will analyze each substance based on its chemical nature.

### Step-by-Step Solution:

1. **Identify the Nature of Each Substance:**
- **HCl (Hydrochloric Acid):** This is a strong acid that dissociates in water to produce H⁺ ions and Cl⁻ ions.
- **NaCl (Sodium Chloride):** This is a salt formed from the neutralization reaction between hydrochloric acid and sodium hydroxide. It dissociates in water to produce Na⁺ ions and Cl⁻ ions, but does not produce H⁺ ions.
- **HNO3 (Nitric Acid):** This is also a strong acid that dissociates in water to produce H⁺ ions and NO3⁻ ions.
