Which one of the following is dispersing medium for Emulsion? A. Gas B. Liquid C. Solid Correct Answer Only B

A colloid is a mixture in which one substance of microscopically dispersed insoluble particles are suspended throughout another substance.

  • Dispersed phase: The phase that is scattered or present in the form of colloidal particles is known as dispersed phase.
  • Dispersion medium: The medium in which the colloidal particles are dispersed is called dispersion medium.

Key Points

Emulsion: An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) owing to liquid-liquid phase separation.

Hence we can conclude that Liquid is dispersing medium for Emulsion. Thus Only B is right option.
