#### Question

The resistance of a conductivity cell containing 0.001M KCl solution at 298 K is 1500 Ω. What is the cell constant if conductivity of 0.001M KCl solution at 298 K is 0.146 × 10^{−3} S cm^{−1}.

#### Solution

Given,

Conductivity, *κ* = 0.146 × 10^{−3} S cm^{−1}

Resistance, *R* = 1500 Ω

∴ Cell constant = *κ* × *R*

= 0.146 × 10^{−3} × 1500

= 0.219 cm^{−1}

Is there an error in this question or solution?
