Vedclass · Answer

(D) Lyophobic sols are solvent-hating and are inherently unstable. They are stabilized only by the presence of an electric charge on the particles. Because they are unstable,they can be easily coagulated by the addition of small amounts of electrolytes. Once coagulated,they cannot be easily reformed into a colloidal state by simply adding the dispersion medium,making them irreversible in nature. Therefore,the statement that they are reversible is incorrect.
