Which statement is true regarding solutions?

• A. They are liquids with dissolved substances
• B. They contain suspended particles
• C. They are always cloudy
• D. They cannot be used for dose adjustment

Answer: (A)

Solutions are homogeneous mixtures formed when a solute dissolves in a solvent, giving a single, uniform phase. In pharmaceutical practice, these are typically liquids in which substances are dissolved, creating a clear, consistent liquid suitable for administration. That’s why describing solutions as liquids with dissolved substances is accurate for common medicinal solutions. Observing suspended particles is a hallmark of suspensions, not solutions, where the solute hasn’t fully dissolved and remains as dispersed particles. Being always cloudy is not correct for solutions, since many are clear and transparent when dissolution is complete. And dose adjustment is often achieved by altering the amount of solution administered or its concentration, so solutions can be used to adjust dose.
