- Non-electrolytes have better coagulating action on colloids than electrolytes
- Sols are coagulated by effective ions whose charge is opposite to that of sol and the ions of higher charge are much more effective than the ions of lower charge
- Charge of the ions has no effect on the coagulation of a sol
- Sols are coagulated only by those ions whose charges is similar to that of the sol
