Adding common salt to distilled water makes it

Options

A. Good conductor of electricity
B. Insulator
C. Can't say
D. None of these

Explanation

To answer the question "Adding common salt to distilled water makes it," we can break down the process step by step:

### Step-by-Step Solution:

1. **Understanding Distilled Water**:
- Distilled water is pure water that does not contain any dissolved salts or impurities. It is a poor conductor of electricity because it lacks ions.

2. **Adding Common Salt (NaCl)**:
- When common salt (sodium chloride, NaCl) is added to distilled water, it begins to dissolve.

3. **Dissociation of Sodium Chloride**:
- Sodium chloride (NaCl) dissociates into its constituent ions when it dissolves in water. This means that NaCl separates into sodium ions (Na⁺) and chloride ions (Cl⁻).

4. **Formation of Ions**:
- The dissociation can be represented by the equation:
\[ \text{NaCl (s)} \rightarrow \text{Na}^+ (aq) + \text{Cl}^- (aq) \]
- Here, (s) indicates solid and (aq) indicates that the ions are in aqueous solution.

5. **Conductivity of the Solution**:
- The presence of these ions (Na⁺ and Cl⁻) in the solution allows it to conduct electricity. This is because electric current is carried by the movement of ions in the solution.

6. **Conclusion**:
- Therefore, adding common salt to distilled water makes it a good conductor of electricity.

### Final Answer:
Adding common salt to distilled water makes it a good conductor of electricity.
