Question

Among the following statements the one which is true for molar conductivity and conductivity is:

• A. Limiting molar conductivity increases with dilution
• B. Conductivity increases with dilution
• C. When concentration approaches unity, molar conductivity is known as limiting molar conductivity
• D. Both a and b are correct

Answer 1

The correct option is A

Limiting molar conductivity increases with dilution

Molar conductivity increases with dilution because the total volume of the solution containing one mole of the electrolyte increases. Conductivity decreases with dilution whereas molar conductivity increases with dilution.
