In a suspension, the solid is dissolved: True or False?

Explanation:
In a suspension, the solid remains undissolved and is dispersed as solid particles in the liquid. Dissolution means the solute dissolves at the molecular level to form a homogeneous solution, which isn’t what happens in a suspension. The dispersed particles are typically larger than a micron and can settle out over time, requiring shaking to re-disperse. Because of this, the statement is false: the solid is not dissolved. This distinction matters in pharmaceutics for understanding solubility, dosing uniformity, and how the product should be stored and administered.
