What does the process of levigation facilitate?

  1. Dissolving gas into a liquid

  2. The grinding process by adding a liquid

  3. Freezing and solidifying mixtures

  4. Evaporation of a mixture's solvent

The correct answer is: The grinding process by adding a liquid

Levigation is a pharmaceutical process that involves the grinding of a substance to a fine powder while adding a liquid (levigating agent) to form a smooth paste. This process facilitates the grinding by reducing friction between the particles and the grinding surface, making the final product smoother and more uniform. Therefore, the correct answer is B because levigation specifically refers to the grinding process with the addition of a liquid. The other options are not related to the process of levigation.
