| List - I | List - II | ||
|---|---|---|---|
| (A) | Lyophilic colloid | (I) | Liquid-liquid colloid |
| (B) | Emulsion | (II) | Protective colloid |
| (C) | Positively charged colloid | (III) | FeCl$_3$ + NaOH |
| (D) | Negatively charged colloid | (IV) | FeCl$_3$ + hot water |
Choose the correct answer from the options given below :
Solution
(A) Protective colloids are lyophilic colloids<br/><br/>
(B) Emulsions are liquid in liquid colloidal
solutions<br/><br/>
(C) FeCl<sub>3</sub> + hot water forms positively charged
colloidal solution of hydrated ferric oxide.<br/><br/>
(D) FeCl<sub>3</sub> + NaOH forms negatively charged
colloidal solution due to preferential adsorption of
OH<sup>-</sup> ions
