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 (0.10 M). If

\lambda _{{x^ - }}^0 \approx \lambda _{{y^ - }}^0

the difference in their pKa values, pKa(HX) - pKa(HY), is (consider degree of ionization of both acids to be << 1)
