Solution
The correct option is C dispersion of precipitate into colloidal state
The dispersion of a freshly precipitated material into colloidal solution by the action of an electrolyte in solution is termed as peptization which involves breaking of suspension into colloidal state by adsorption of suitable ions and electricxally charged particles then split from the precipityate as colloidal particles.
The dispersion of a freshly precipitated material into colloidal solution by the action of an electrolyte in solution is termed peptization. The electrolyte used is called a peptizing agent. For Exaample, sols obtained by peptisation are: Freshly prepared ferric hydroxide on treatment with a small amount of ferric chloride solution at once forms a dark reddish brown solution. Ferric chloride acts as peptizing agent.
The process of converting a precipitate into colloidal sol by shaking with dispersion medium in the presence of a small amount of electrolyte is called peptization.
Process of peptization:
The precipitate adsorbs electrolyte ions on its surface. This causes the development of positive or negative charge on precipitates, which ultimately break up into smaller particles of colloid size.
Example:
Freshly precipitated Fe(OH)3 is shaken with aqueous solution of FeCl3.
