Vedclass · Answer

(B) The process of converting a freshly prepared precipitate into a colloidal solution by adding a suitable electrolyte (called a peptizing agent) is known as $Peptization$. The reverse process,where a colloidal solution is converted into a precipitate by adding an electrolyte,is known as $Coagulation$ or $Flocculation$. $Precipitate \xrightarrow{	ext{Peptization}} 	ext{Colloidal solution}$ $	ext{Colloidal solution} \xrightarrow{	ext{Coagulation/Flocculation}} 	ext{Precipitate}$
