Which of the following is a property of lyophilic colloids?

The difference between colloids and crystalloids is based on

Electrophoresis is used

The migration of dispersion medium under the influence of an electric potential is called

The number of positively and negatively charged sols respectively in the following are $TiO_2$,blood,$CdS$,$Cu$,$Ag$,Clay,$SiO_2$,$Fe_2O_3$.

In each of four separate beakers $(I, II, III, IV)$,$X \ mL$ of $y \ M \ Fe_2O_3 \cdot xH_2O$ colloidal solution is present. Equal volume and equal concentration of $KCl, K_4[Fe(CN)_6], K_3PO_4$ and $K_2SO_4$ were added into $I, II, III$ and $IV$ respectively. The efficiency of precipitation in these beakers follows the order:
