Which of the following solutions of KCl has the lowest value of specific conductance ?

Options

A. 1M
B. 0.1 M
C. 0.01 M
D. 0.001 M

Answer

To determine which solution of KCl has the lowest specific conductance, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Specific Conductance**:
Specific conductance (K) is defined as the ability of a solution to conduct electricity. It is given by the formula:
\[ K = \Lambda_m \times C \]
where \( \Lambda_m \) is the molar conductivity and \( C \) is the concentration of the solution in moles per liter (M).

2. **Identify the Relationship**:
Specific conductance is directly proportional to the concentration of the solution. This means that as the concentration of the solution increases, the specific conductance also increases.

3. **Evaluate the Options**:
If we are given multiple options for KCl solutions with different concentrations, we need to identify which option has the lowest concentration. The specific conductance will be lowest for the solution with the lowest concentration.

4. **Choose the Correct Option**:
From the options provided, identify the one with the lowest concentration of KCl. This will be the solution with the lowest specific conductance.

5. **Final Answer**:
Based on the analysis, the option with the lowest concentration of KCl will have the lowest specific conductance.

### Conclusion:
Thus, the solution of KCl with the lowest concentration will have the lowest specific conductance.
