In a suspension, how are the solid particles described after preparation?

• A. The solid particles are dissolved
• B. The solid particles are dispersed but not dissolved
• C. The solid particles are vaporized
• D. The solid particles are reacted

Answer: (B)

Solid particles in a suspension are dispersed in the liquid but not dissolved. In a suspension, the solid remains as discrete particles that are physically carried by the liquid, forming a heterogeneous mixture. Because the particles are not dissolved, they can be visible and may settle out over time unless the suspension is stirred or stabilized. This is different from a solution, where the solute is dissolved at the molecular level. The other options imply phase changes or chemical transformation (vaporization, reaction) or complete dissolution, which do not describe a suspension.
