Question

At 298 K, the electrolytic conductivity of a 0.2 M KC1 solution is 2.50 X 10^-2S cm^-1. Calculate its molar conductivity.

Expert Solution

Step 1

The molar conductivity $λ_{m}$ of a solution represents the conducting ability of all the ions produced from one mole of the electrolyte in the solution. The expression for molar conductivity is given as:

$M o l a r c o n d u c t i v i t y λ_{m} = \frac{k \times 1000}{C}$

Here 'k' = conductivity of the solution

'C' = concentration of the solution
