Read the passage given below and answer the following questions:
The cell constant is usually determined by measuring the resistance of the cell containing a solution whose conductivity is already known. For this purpose, we generally use KCl solutions whose conductivity is known accurately at various concentrations and at different temperatures. Consider the resistance of a conductivity cell filled with 0.1 M KCl solution is 200 Ohm. If the resistance of the same cell when filled with 0.02 M KCl solution is 420 Ohm. (Conductivity of 0.1 M KCl solution is 1.29 S m–1.)

Answer:

To determine the conductivity of a 0.02 M KCl solution, we can use the given information about the resistance of the conductivity cell filled with the solution.

1. Given Information:
- Resistance of the cell filled with 0.1 M KCl solution = 200 Ohm
- Resistance of the same cell filled with 0.02 M KCl solution = 420 Ohm
- Conductivity of 0.1 M KCl solution = 1.29 S m–1

2. Understanding Conductivity and Resistance:
- Conductivity is the measure of a solution's ability to conduct electric current.
- Resistance is the measure of how much a substance or material impedes the flow of electric current.
- Conductivity and resistance are inversely proportional to each other.

3. Calculating the Conductivity of 0.02 M KCl Solution:
- We can use the concept of proportionality between conductivity and resistance to calculate the conductivity of the 0.02 M KCl solution.
- Let's assume the conductivity of the 0.02 M KCl solution as 'x' S m–1.
- According to the given information, the resistance of the cell filled with the 0.1 M KCl solution is 200 Ohm, and the resistance of the same cell filled with the 0.02 M KCl solution is 420 Ohm.
- Using the formula for resistance and conductivity, we have:
- Resistance = 1 / Conductivity
- Resistance of 0.1 M KCl solution = 1 / 1.29 S m–1
- Resistance of 0.02 M KCl solution = 1 / x S m–1
- Now, we can set up a proportion to find the value of 'x':
- Resistance of 0.1 M KCl solution / Resistance of 0.02 M KCl solution = Conductivity of 0.02 M KCl solution / Conductivity of 0.1 M KCl solution
- 200 Ohm / 420 Ohm = x S m–1 / 1.29 S m–1
- Solving for 'x', we get:
- x = (200 Ohm / 420 Ohm) * 1.29 S m–1
- x = 0.614 S m–1

4. Conclusion:
- Therefore, the conductivity of the 0.02 M KCl solution is 0.614 S m–1, which matches with option 'C'.
