Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Dear Dibya Ranjan,
Greetings!
Here is the solution of your query.
According to the Basic Law of Electrochemistry:
i.e. , Specific conductance (K, kappa) is equal to the product of the conductance of the electrolyte and the cell constant.on dividing Specific conductance by Conductance)is known accurately at various concentrations and at different temperatures.
Specific conductance (K, kappa) = C. l/a.
Where l/a is cell constant.
Or cell constant= Specific conductance/ Conductance.
(Cell constant can be determined
The cell constant is usually determined by measuring the resistance of the cell containing a solution whose conductivity is already known. For this purpose,
We generally use KCl solutions whose conductivity
The standard values of specific conductance of KCl solutions at different concentrations are known.
Thank you for asking your query.
