Question

Explain the difference of molar conductivity in dillusion for strong and weak electrolyte?

Answer 1

Are there not MORE charged particles in the strong electrolyte?

Explanation:

Take sodium acetate, and acetic acid: sodium acetate completely ionizes in solution to give TWO charged particles:

`H_3C-CO_2^(-)Na^(+) rarrH_3-CO_2^(-) + Na^(+)`

On the other hand, the parent molecule only INCOMPLETEY ionizes:

`H_3C-CO_2H + H_2O(l) rightleftharpoonsH_3-CO_2^(-) + H_3O^+`

And this equilibrium lies to the left. Since the former solution contains MANY more charged particles capable of bearing a current, the sodium acetate solution is more conductive..
