Which term describes a mixture with visible particles that can be easily separated?

• A. Colloid
• B. Acid
• C. Solute
• D. Suspension

Answer: (D)

Mixtures are distinguished by particle size and whether the particles settle out. A suspension describes a mixture where the particles are large enough to be seen and are not dissolved, so they tend to settle out over time. Because the solid particles are visible and not dissolved, you can separate the components by letting them settle, decanting, or filtering. Classic examples include muddy water or sand in water, where you can clearly see the grains and they eventually sink, making separation straightforward. This visible, easily separable behavior is what defines a suspension. In contrast, a colloid has smaller particles that don’t settle quickly and can’t be separated by simple filtration, and a solution involves dissolved particles you can’t see; an acid is a chemical substance, not a mixture of visible particles.
