Question

Select the correct statement. (A) Conductivity decreases but molar conductivity increases with increase in dilution (B) Conductivity increases but molar conductivity decreases with increase in dilution (C) Conductivity decreases but molar conductivity increases with increase in concentration (D) Conductivity as well as molar conductivity decrease with decrease in concentration

Tardigrade Admin · Accepted Answer

Conductivity always decreases with decrease in concentration because the number of ions (current carrying species) per unit volume decreases on dilution. Molar conductivity, however, increases on dilution because total volume of solution containing one mole of electrolyte also increases.
