What is spatulation primarily used for?

  1. Grinding crystalline powders

  2. Mixing ingredients on an ointment slab

  3. Dissolving a solute in a solvent

  4. Creating a suspension

The correct answer is: Mixing ingredients on an ointment slab

Spatulation is a technique used in pharmacy and laboratory settings to mix ingredients on an ointment slab. This involves using a spatula to spread and blend substances together until a uniform mixture is achieved. Option A, grinding crystalline powders, would involve crushing or breaking down particles rather than mixing them. Option C, dissolving a solute in a solvent, would not require the use of a physical tool like a spatula. Option D, creating a suspension, can involve the use of a spatula in some cases, but is not the primary purpose of spatulation.
