For weak electrolyte, sudden increase in molar conductance with dilution. Prove this statement. |
|
Answer» SOLUTION :For a weak electrolyte, at high CONCENTRATION the plot is almost parallel to concentration axis with slight increase in CONDUCTIVITY as the dilution INCREASES. When the concentration approaches zero, there is a sudden increase in the molar conductance and the curve is a almost parallel to `Lambda_m` axis. This is due to the fact that the DISSOCIATION of the weak electrolyte increases with the increase in dilution (Ostwald.s dilution law). |
