A : Starch and gelatin are loyophillic colloid. R : They have strong interaction, with the dispersion medium

each question constain STATEMENT-1(Assertion ) and STATEMENT - 2 (reason). examine the statement carefully and work the correct answer accoridng to the instructions given below : STATEMENT-1: Protein, starch are lyophilic colloids. STATEMENT-2: They have strong interaction with the dispersion medium.

Assertion (A): Most of the solids possess high melting point. Reason (R): They have strong intermolecular forces of attraction.

Assertion: Lyophilic colloids are more stable than lyophobic colloids. Reason: In lyophobic system, the dispersed particles are more solvated than in lyophilic system.

(i) Assertion: Lyophilic sols are reversible in nature. Reason: In Lyophilic sols particles of dispersed phase have great affinity for the dispersion medium.

Assertion : Gelatin is often used as a protective colloid. Reason : Protection is the property of lyophilic colloids.

Assertion :- Lyophilic sol is more stable than lyophobic sol. Reason :- Lyophilic sol have greater solvation energy then lyophobic sol.
