Vedclass · Answer

(C) $1$. Colloidal solution is a mixture in which tiny particles are suspended in a liquid substance. The suspended particles are known as the dispersed phase and the liquid substance is known as the dispersion medium.$2$. Colloidal sols are classified as Lyophobic (liquid-hating) and Lyophilic (liquid-loving). Lyophilic sols are inherently more stable due to the high affinity between the dispersed phase and the dispersion medium.$3$. Egg white contains albumin,which acts as a protective colloid and forms a lyophilic sol when mixed with water. This provides stability to the colloidal system.$4$. Therefore,egg white ensures the stability of the red ink sample.$5$. $HCHO$,eosin dye,and water do not possess the property of stabilizing the colloid in this mixture.Thus,option $(C)$ is correct.

$A$ sample of red ink (a colloidal solution) is prepared by mixing eosin dye,egg white,$HCHO$ and water. The component which ensures stability of the ink sample is :-
