The formation of this film around dispersed phase colloidal particles is called solvation. The stability of lyophilic sol is due to solvation. WebAn emulsion is formed in both the tubes. The oil separates out in the tube in which- alkali has not been added while in the other tube the emulsion is stabilized. Inference: The shaking of oil with water does not necessarily make an emulsion, for, the oil and water soon separate into two layers when allowed to settle. northgate mall durham

WebEmulsions are a type of colloid. Emulsions are an example of colloids composed of tiny particles suspended in another immiscible (unmixable) material. An emulsion is a suspension of two liquids that usually do not mix together. These liquids that do not mix are said to be immiscible. An example would be oil and water.
