A 0.100 M KCl solution is placed in contact with a 0.100 M LiCl solution.Which of the following is true for junction between the two solutions?
I The KCl side of the junction will be positive as Cl⁻ diffuses faster across the junction than K⁺.
II The LiCl side of the junction will be negative as Li⁺ diffuses faster across the junction than K⁺.
III The KCl side of the junction will be positive as K⁺ diffuses slower across the junction than Li⁺
IV The LiCl side of the junction will be more negative as Li⁺ diffuses faster across the junction than Cl⁻.
