The "isoelectric point" of a colloidal particle refers to the pH at which:
The particle has no charge and is electrically neutral
The particle has the highest positive charge
The particle has the highest negative charge
The particle is at its highest stability
The isoelectric point is the pH at which the colloidal particle carries no net charge, and the electrical double layer collapses. At this point, the colloidal particles tend to aggregate and coagulate.
Hence option 1 is correct.
