The equivalent conductance and molar conductance of caso4 are related as
Answers
Answer:
Conductivity changes with the concentrationof the electrolyte. The number of ions per unit volume carrying the current decreases on dilution, so conductivity always decreases with decrease in concentration. However, molar conductivity increases with dilution.
Hence the number of ions per unit volume that carry charge in a solution decreases. As the movement of these charges towards the oppositely charged electrodes causes the flow of current, the conductivity of a solution decreases on dilution. We need to be clear about the definition, that says : Molar conductivity is the conductance of the volume of the solution containing 1 mole of electrolyte...
As the total volume of solution containing one mole of electrolyte increases, the decrease in conductivity due to dilution is more than compensated by increase in its volume of solution that contains one mole of the electrolyte.

Conductivity changes with the concentration of the electrolyte. The number of ions per unit volume carrying the current decreases on dilution, so conductivity always decreases with decrease in concentration.
However, molar conductivity increases with dilution. This is because conductivity of a solution is the conductance of one unit volume of the solution, but molar conductivity is the conductance of that volume solution containing one mole of electrolyte.
