Which outcome occurs when water contacts concentrated potassium chloride across polymer film?

A)Water electrolysis at opposing interfaces
B)Selective ion transport across membrane
C)Liberation of chlorine and potassium gas
D)Exothermic, spontaneous nucleophilic substitution

💡 Explanation

Selective ion transport occurs because the polymer permits passage based on sizes/charge, which is Ion-Selective Permeation. Therefore the smaller hydrated potassium and chloride progress across, rather than electrolysis, which requires external redox conditions.
