Question

Define the term cell constant. The specific conductivity of a 0.3N KCI solution at 27 C is 0.028 mho/cm-1. Resistance of the cell containing this solution is 300ohms. Determine cell constant,​

Answer 1

Answer:

Cell constant is defined as the ratio of the distance between conductance-titration electrodes to the area of electrodes, measured from the determined resistance of the solution of specific conductance. Unit of cell constant is cm-1
