← ScienceWhich 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.
