The molar conductivity of a solution of a weak acid HX(0.01 M) is 10 t – InterviewSolution

1.	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 λ∘X−≈λ∘Y−, the difference in their pKa values, pKa(HX)−pKa(HY), is (consider degree of ionizaiton of both acids to be
Answer» The molar conductivity of a solution of a weak acid $H X (0.01 M)$ is 10 times smaller than the molar conductivity of a solution of a weak acid $H Y (0.10 M)$ . If $λ_{X^{-}}^{\circ} \approx λ_{Y^{-}}^{\circ}$ , the difference in their $p K_{a}$ values, $p K_{a} (H X) - p K_{a} (H Y)$ , is (consider degree of ionizaiton of both acids to be <<1)
