MCQ
As dilution of the solution increases then the conductivity of solution $......$
  • ✓
    Increases.
  • B
    Decreases.
  • C
    Remain unchanged.
  • D
    None of the above.
✓

Answer

Correct option: A.
Increases.
The conductivity of a weak electrolyte increases with an increase dilution. As the dilution increases the number of ion increases and they get free from their co$-$ions and can move independently from each other. So by increasing dilution the rate of conductivity increases as more ions are available for conductance.
