2The sol does not have a definite structure.The gel possesses honeycomb like structure.
3The dispersion medium of the sol may be water (hydrosol) or alcohol (alcosol).The dispersion medium of gel will be hydrated colloid particles.
4The sol can be converted to gel by cooling.The gel can be converted to sol by heating.
5The sol can be easily dehydrated.The gel cannot be dehydrated.
6The viscosity of the sol is very low.The viscosity of the gel is very high.
7Sol is categorized into lyophobic and lyophilic sols.There is no such classification of gel.
