It os practically difficult to calculate the equivalent conductivity of a weak electrolyte in aqueous solutions. Comment.

Explanation

Equivalent conductance ` = ( k xx 1000) `/ normality. The extent of dissociation of a wea electrolyte is less. Accordingly the number of ions furnished in aqueous solution is less. The specific conductivity (k) of a weak electrolyte is in the order `10^(-2)S m^(-1)` of or less. Since k is less, it is difficult to calculate equivalent conductivity of a weak electrolyte.
