what is lyophobic colloid ?
In this colloidal system, the dispersed phase does not have an affinity for the dispersion medium so the colloid is not readily formed. They are also known as irreversible sols as they cannot be reconstituted by simply adding dispersion medium after precipitation.
Lyophobic colloids are liquid hating colloids (Lyo means solvent and phobic means hating). ... Of the given solution the gold sol is lyophobic colloidal solution.
Gold particles have very less affinity towards dispersion medium, hence its sol can be easily coagulated.
