Chemistry Question on Electrochemistry
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 x 10-3 S cm-1 .
Answer
Given,
Conductivity, k = 0.146 × 10-3 S cm-1
Resistance, R = 1500 Ω
Cell constant = k × R
= 0.146 × 10-3 × 1500
= 0.219 cm -1
