Problem

The molar conductivity of a solution of a weak acid HX (0.01 M) is 10 times smaller than the molar conductivity of a solution of a weak acid HY (0.1 M). If λX−0≈λY−0\lambda_{X^-}^0 \approx \lambda_{Y^-}^0 , the difference in their pKapK_a values pKa(HX)−pKa(HY)pK_a(\text{HX}) - pK_a(\text{HY}) , is (consider degree of ionization of both acids to be ≪1\ll 1 )
