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?
