Vedclass · Answer

(B) The molar conductivity at infinite dilution $(\wedge^{\infty})$ for a weak electrolyte like $AgCl$ cannot be determined by the extrapolation of the $\wedge$ vs $\sqrt{C}$ graph because the graph does not become linear at low concentrations.According to Kohlrausch's Law of independent migration of ions,$\wedge^{\infty}$ for any electrolyte can be calculated using the limiting molar conductivities of its constituent ions.For $AgCl$,we can use the values of strong electrolytes: $\wedge^{\infty}_{AgCl} = \wedge^{\infty}_{AgNO_3} + \wedge^{\infty}_{HCl} - \wedge^{\infty}_{HNO_3}$.Thus,option $(B)$ is correct,while option $(A)$ is incorrect for $AgCl$.

$\wedge_{AgCl}^{\infty}$ can be obtained by:
