Lyophilic Colloids Vs Lyophobic Colloids

Lyophilic Colloids	Lyophobic Colloids
The colloidal solutions in which the particles of the dispersed phase have a great affinity for the dispersion medium are called lyophilic colloids.	The colloidal solutions in which there is no affinity between particles of the dispersed phase and the dispersion medium are called lyophobic colloids.
These are easily formed by direct mixing.	These are formed only by special methods.
The particles of colloids are true molecules and are of big size.	The particles are aggregates of many molecules.
The particles are not easily visible even under ultra-microscope.	The particles are easily detected under ultra-microscope.
These are very stable.	These are unstable and requires traces of stabilizers.
They are not easily precipitated by small amount of electrolytes. Very large quantities of electrolytes are required to cause coagulation.	They are easily precipitated by the addition of small amount of suitable electrolytes.
These are reversible in nature i.e., once precipitated can reform the colloidal sol by simply remixing with the dispersion medium.	These are irreversible in nature i.e., once precipitated cannot form the colloidal sol by simply addition of the dispersion medium.
These particles do not carry any charge. The particles may migrate in any direction or even not under the influence of an electric field.	These particles move in a specific direction i.e., either towards anode or cathode depending upon their charge.
The particles of colloids are heavily hydrated due to the attraction for the solvent.	The particles of colloids are not appreciably hydrated due to the hatred for the solvent.
The viscosity of the sols is much higher than that of the dispersion medium.	The viscosity is nearly the same as that of the dispersion medium.
The surface tension is usually lower than that of the dispersion medium.	The surface tension is almost the same as that of the dispersion medium.
They do not show Tyndall effect.	They show Tyndall effect.
