Sols and gels are fairly interrelated conditions since they each are lyophilic colloids. Gel is really a strong or semisolid condition of colloidal solution, although sol is its liquid condition. Equally protein and starch can be employed in the shape of sol or gel.

Gels are elements made up of a three-dimensional crosslinked polymer or colloidal community immersed inside a fluid. They usually are soft and weak, but might be made tricky and hard. Hydrogels are gels which have drinking water as their principal constituent.

This can be the origin of both gel and rubber elasticity. But one particular key variation is the fact that gel is made up of an additional solvent stage and hence is able to owning considerable quantity alterations under deformation by using out and in solvent. For instance, a gel could swell to many situations its initial volume immediately after becoming immersed in a solvent immediately after equilibrium is attained.
