When water is added to an aqueous solution of an electrolyte, what is the change in specific conductivity of the electrolyte?

Options

A. Conductivity decreases
B. Conductivity increases
C. Conductivity remains same
D. Conductivity does not depend on number of ions.

Explanation

To solve the question regarding the change in specific conductivity of an electrolyte when water is added to its aqueous solution, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Specific Conductivity**:
- Specific conductivity (κ) is defined as the ability of an electrolyte solution to conduct electricity, which depends on the concentration of ions in the solution.

2. **Effect of Adding Water**:
- When water is added to an aqueous solution of an electrolyte, the total volume of the solution increases. This dilution affects the concentration of ions present in the solution.

3. **Concentration of Ions**:
- The concentration of ions in the solution is defined as the number of ions per unit volume. When we add water, the number of ions remains the same, but the volume increases, leading to a decrease in the concentration of ions.

4. **Impact on Conductivity**:
- Since specific conductivity is directly proportional to the concentration of ions, a decrease in ion concentration results in a decrease in specific conductivity. Therefore, as the concentration of ions decreases, the specific conductivity (κ) also decreases.

5. **Conclusion**:
- Thus, when water is added to an aqueous solution of an electrolyte, the specific conductivity of the electrolyte decreases.

### Final Answer:
- The specific conductivity of the electrolyte decreases when water is added to its aqueous solution.
