The dissociation constant of n-butyric acid is `1.6 xx 10^(-5)` and the molar conductivity at infinite dilution is `380 xx 10^(-4) Sm^(2) mol^(-1)`. The specific conductance of the `0.01M` acid solution isA. `1.52 xx 10^(-5) S`B. `1.52 S`C. `1.52 xx 10^(-3) S`D. `1.52 xx10^(-4) S` |

Answer» Correct Answer - B `alpha = sqrt(K_(alpha))/(C ) = sqrt(1.6 xx10^(-5))/(0.01)` `lambda_(m) = alphal lambda_(m)^(@) = (K xx 1000)/("molarity")` when `lambda_(m)` is in `S cm^(2)mol^(-1)` `G = (K)/("cell constant")` |
