Question

Peptization denotes:
(A) Digestion of food
(B) Hydrolysis of proteins
(C) Breaking and dispersion into colloidal state
(D) Precipitation of solid from colloidal dimension

Answer 1

Hint Before solving this question, we should understand the definition of colloidal solution and also that the colloidal solution is a heterogeneous mixture.

Complete solution:
Peptization is the process in which collisions are formed from the precipitate with the help of electrolyte when we shake the solution properly. The electrolyte which is used in the process of peptization is known as peptizing agent. Some of the most commonly used peptizing agents are sugar, gelatin etc.
The charge of peptization is determined when we will use the electrolyte having the same charge because the electrolyte will be observed by the precipitation then the particles will bear the same charge.

Hence, the correct answer is option (C) i.e. precipitation denotes Breaking and dispersion into colloidal state.

Additional information:
Colloidal solution is a heterogeneous mixture in which the dispersed particles are present in the intermediate size between those of a solution and a suspension. Colloidal particle is a mixture in which the substance is regularly suspended in a fluid. In a colloidal solution, the units or the particles are bigger and do not liquify but come to be equally dispersed all through a liquid.

Note: The most common example of peptization is clay. Clay is generally used to make pottery. Peptization is also different from flocculation because in flocculation the collides are obtained from the suspension in an aggregate form.
