Question

 From the following data, calculate the molar conductivity of NaCl in aqueous solution:

Conductivity of 4.0 × 10-4 mol dm-3 NaCl solution = 6.20 × 10-3 S m⁻¹

Conductivity of the water = 0.05 × 10-3 S m⁻¹.

The molar conductivity of an electrolyte is obtained from the measured conductivity after correcting for the contribution of the solvent and relating it to the concentration of the solution. In the present case, the specific conductivity of the aqueous sodium chloride solution is given as 6.20 × 10⁻³ S m⁻¹, while pure water shows a conductivity of 0.05 × 10⁻³ S m⁻¹ due to the _________ _______ _________ _________ __________ ______ _____ ___.
