By diluting a weak electrolyte , specific conductivity K c and equivalent conductivity ( λ c ) change as-

Options

  1. ABoth increase
  2. BK c increases, λ c decreases
  3. CK c decreases, λ c increases
  4. DBoth decrease

Correct answer

C. K c decreases, λ c increases

Step-by-step solution

When the solution of a weak electrolyte is diluted, the volume of the solution increases, hence equivalent conductivity ( λ c ) increases. However, during this process, the number of current carrying particles per c m 2 decreases, hence specific conductivity K c decreases.
