Adding common salt to distilled water makes it

Options

A. Good conductor
B. Insulator
C. No
D. Both (a) and (b)

Answer

To solve the question "Adding common salt to distilled water makes it," we will analyze the properties of distilled water and the effect of adding common salt (sodium chloride, NaCl) to it.

### Step-by-Step Solution:

1. **Understanding Distilled Water**:
- Distilled water is the purest form of water, which means it does not contain any dissolved salts or impurities.
- As a result, distilled water does not conduct electricity well because it lacks free ions.

2. **Adding Common Salt**:
- When we add common salt (NaCl) to distilled water, it dissolves in the water.
- The dissolution of NaCl in water breaks it down into its constituent ions: sodium ions (Na⁺) and chloride ions (Cl⁻).

3. **Formation of Ions**:
- The presence of these ions in the solution is crucial because ions are responsible for conducting electricity.
- In pure distilled water, there are no ions available to carry electric current, but the addition of NaCl introduces these charged particles.

4. **Conductivity of the Solution**:
- With the formation of Na⁺ and Cl⁻ ions, the solution can now conduct electricity.
- Therefore, the solution of distilled water with added common salt becomes a good conductor of electricity.

5. **Conclusion**:
- Based on the above analysis, we conclude that 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.
