The sequence of ionic mobility in aqueous solution is

Options

  1. ANa ⁺> K ⁺> Rb ⁺> Cs ⁺
  2. BK ⁺> Na ⁺> Rb ⁺> Cs ⁺
  3. CCs ⁺> Rb ⁺> K ⁺> Na ⁺
  4. DRb ⁺> K ⁺> Cs ⁺> Na ⁺

Correct answer

C. Cs ⁺> Rb ⁺> K ⁺> Na ⁺

Step-by-step solution

More the charge density of ion, more will be the ion-dipole interaction, so more will be hydration of ion and hence less will be the ionic mobility.
