The negative charge on the silicate clays develops due to unsatisfied valences at the broken edges of silica and aluminium sheets. Besides, the flat external surfaces of silicate clay minerals also serve as the sources of negative charge. Ionizable hydrogen ions are hydrogen’s from hydroxyl ions on clay surfaces.
