Answer» Correct Answer - A Imagine `1 C C` of a solution of an electrolyte placed between two large electrode `1 cm` apart. The cross-sectional area of the solution will be `1 cm^(2)`. The conductance of the solution `(G = kappa.l//A)` with evidently be its specific conductance because we are having one `cm` cube of the solution. Further, suppose that `1 CC` of the solution contains `1` gram equivalent of the electrolute dissolved in it. Then, according to the definition of equivalent conductance (the conducting power of all ions produced by one equivalent of the electrolyte in the given solution), the conductance, `Lambda_(eq.)` Thus, in this case Conducatance (G) = Specific conductance `(kappa)` = Equivalent conducatance `(Lambda_(eq.))` |
