Problem 12
Which of the following postulatales of Debye-Huckel theory is/are true? (a) The strong electrolyte is completely ionised at all dilutions. (b) The oppositely changed ions are completely distributed in the solution but the cations tend to be found in the vicinity of anions and vice versa. (c) Decrease in equivalent conductance with increase in concentration is due to fall in mobilities of ions due to inter-ionic effect. (d) All of the above.
Problem 14
The effect that trends to retard the mobilities of ions in solution is (a) asymmetry effect (b) relaxation effect (c) electrophoretic effect (d) all of these
Problem 15
If \(\lambda_{\infty}\) and \(\lambda_{v}\) are the equivalent conductances at infinite dilution and at \(V\) dilution, the degree of dissociation, \(\alpha\) is given by (a) \(\alpha=\frac{\lambda_{\infty}}{\lambda_{v}}\) (b) \(\alpha=\frac{\lambda_{c 0}}{\lambda_{v}^{2}}\) (c) \(\alpha=\frac{\lambda_{v}}{\lambda_{\mathrm{cos}}}\) (d) None of these
