Experiment 5
OBJECT
Determination of the cell constant at different concentrations and infer the results obtained.
THEORY
Cell Constant
If R is the resistance of a solution measured by a cell with electrodes of cross-sectional area a cm2 and l cm apart, the specific conductivity of the solution is given by,
where 
is the cell constant.
The cell constant, i.e., the ratio l/a, cannot be obtained from the geometrical dimensions of the cell, as both l and a, they are not accurately known. It is, therefore, necessary to calibrate the cell with ...
