How does molar conductivity vary with concentration for strong and weak electrolytes? Explain?
Asked by Topperlearning User | 16th Jun, 2014, 10:17: AM
The strong electrolytes are almost completely ionized in aqueous solution at all concentrations. So generally they have a high value of m even at high concentrations. But, in concentrated solutions of strong electrolytes the density of ions is quite high which results in inter-ionic interactions. Due to these interactions, the value of m lowers at high concentrations. On increasing dilution the ions move apart which leads to the increase in the value of m. The molar conductivity of a weak electrolyte increases with decrease in concentration.
