The correct Answer is:
To determine the correct statement about lyophilic sols, let's analyze each option step by step. ### Step 1: Understand what lyophilic sols are Lyophilic sols are colloidal systems where the dispersed phase (solid) has a strong affinity for the dispersion medium (liquid). This strong attraction results in a stable colloidal system. ### Step 2: Evaluate each option **Option (a): Irreversible sols** - Lyophilic sols are not irreversible; they are reversible. When the dispersion medium is removed, they can reform when the medium is reintroduced. Therefore, this statement is **false**. **Option (b): Prepared from inorganic compounds** - Lyophilic sols are typically prepared from organic compounds, not inorganic ones. They are formed from substances that have a strong affinity for the solvent (liquid-loving). Thus, this statement is also **false**. **Option (c): Coagulated by adding electrolytes** - While it is true that electrolytes can cause coagulation, lyophilic sols require a large amount of electrolytes to achieve this due to the strong attraction between the dispersed phase and the medium. A small amount of electrolyte will not cause coagulation. Therefore, this statement is **false**. **Option (d): Self-stabilizing** - Lyophilic sols are indeed self-stabilizing due to the strong interactions between the dispersed phase and the dispersion medium. This stability means they do not easily coagulate and maintain their colloidal form. Thus, this statement is **true**. ### Conclusion The correct answer is **(d) Self-stabilizing**.
