, Colloid Chemistry
• Definition
• Components of colloids
• Classification of colloids (based on phase)
• Classification of colloids (based on the force of
attraction between dispersed phase and
dispersion medium)
• Properties of lyophobic and lyophilic colloids

, Definition
• Colloidal solutions seems to be homogeneous
to the naked eye but appears to be
heterogeneous when observed through an
ultra-microscope.
• Intermediate solution between true solution
and suspension.
