Question: Differentiate between lyophilic and lyophobic colloids?
Lyophilic colloids are colloids where the particles have an affinity for and are soluble in the dispersion medium. These colloids are referred to as “soluble colloids” and their particles stay suspended in the dispersion medium. Examples of lyophilic colloids include gels and emulsions.
Lyophobic colloids are colloidal dispersions in which the particles tend not to be soluble in the dispersion medium. Because of this, the particles are much more difficult to disperse and stay suspended and therefore tend to sediment more quickly. Examples of lyophobic colloids include colloidal silicon dioxide and silica gel.
