Dispersion is the act of scattering or spreading something widely. Thus, the term dispersible refers to substances that are easily spread or dissolved in a liquid. Some synonyms for dispersible include soluble, dissolvable, soluble in water, miscible, emulsifiable, and diffusible. These words signify the ability of a substance to dissolve or spread easily in a liquid medium without clumping or settling down. For instance, sugar, salt, and aspirin are dispersible in water while oil is not. The dispersible property of a substance is essential in many applications, such as in the formulation of pharmaceuticals, food products, and industrial chemicals.
