1.	Which of the following equations corrects the molar conductivity with concentration for a strong electrolyte?A. `Lambda_(m)^(0) = Lambda_(m) - AsqrtC`B. `Lambda_(m) = Lambda_(m)^(0) - AsqrtC`C. `Lambda_(m) = Lambda_(m)^(0) - AsqrtC`D. `Lambda_(m) = Lambda_(m)^(0) + AsqrtC`
Answer» Correct Answer - C This emirical formula was given by Kohlrausch on the basis of his experimental results. A is a constant, its value depends on the nature of the electrolyte rather than on the identity of the specific ions. For example, electrolytes of the type `KCl, NaOH`, etc. have the same value of `A` while `BaCl_(2), CuSO_(4)` etc. gave a different value.
