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

Explanation

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