प्रश्न
Give reasons:
In the experimental determination of electrolytic conductance, Direct Current (DC) is not used.
उत्तर
If direct current is utilized in the experimental determination of electrolytic conductance, it might create polarisation of the electrodes and electrolyte, resulting in an inaccuracy in conductance measurement.
