The term that describes the distribution of a solute in a solvent is:

• A. Absorption
• B. Distribution
• C. Disintegration
• D. Dissolution

Answer: (D)

Dissolution is the process by which a solute goes into solution in a solvent, becoming distributed throughout the solvent at the molecular level. It describes how the solid, liquid, or gas dissolves to form a homogeneous solution, with the rate and extent influenced by solubility, temperature, agitation, particle size, and the nature of the solvent. This differs from absorption (uptake into the bloodstream), distribution (dispersion within body compartments after absorption), and disintegration (breaking down of a dosage form). So the term that matches “the distribution of a solute in a solvent” is dissolution.
