The resistance of a conductivity cell containing 0.001M KCl solution is 1500 ohm. What is the cell constant if conductivity of the solution at 298K is 0.000146 S/cm.
Given,
Resistance (R) = 1500 ohm
Conductivity of solution = 0.000146 S/cm
We know that,
Conductivity = (1/Resistance) × Cell constant
Cell constant = Conductivity × Resistance
Cell constant = 0.000146 × 1500 = 0.219 cm-1
