Which Colloids Cannot Be Easily Coagulated?

Explanation: Lyophilic colloids are formed directly by mixing of dispersed phase and dispersion medium. They are quite stable and thus cannot be coagulated easily. ... Lyophobic colloids are also called as irreversible colloids in nature i.e. they can not be reformed if they are precipitated by simple mixing.

Which colloids can be easily coagulated?

Hydrophobic sols get easily coagulated because these sols are stabilized due to the charge on the particle. If the charge is removed by adding any suitable electrolyte the particles tend to come closer and form aggregate or precipitate.

Which of the following is not easily coagulated?

Macromolecular colloids cannot be easily coagulated since they are quite stable.
