Which of the following statement is wrong in the context of molar conductance?A. The solution should contain one mole of the electrolyteB. The distance the electrodes should be `1 cm`C. The area of he electrodes should be large enugh for the solution to touch completelyD. The volume of the solution should be very small. |

Answer» Correct Answer - D Molar conductance is the conductance of a solution between two electrode spaced one centrimeter apart which enclose one mole of the electrolyte between them. Since the conductivity, `kappa` is the conductance of the cubic centimeter of solution between one centimeter apart, it follows that `Lambda_(m) = kappaV` wherer `V`(dilution) is the volume in `cm^(3)` containing one mole of electrolyte. |
