Question

What is one property of a suspension that is different from that of a solution or a colloid?

• A. Suspensions are colourless.
• B. A suspension is always clear.
• C. Particles cannot be seen in a suspension with a naked eye.
• D. The particles of a suspension will settle out if left untouched.

Answer 1

The correct option is D

The particles of a suspension will settle out if left untouched.

Suspensions have the largest particle size as compared to colloids and solutions. As such, these particles tend to settle after some time due to gravitational forces acting on the particles. So, the particles in the suspension are unstable and settle down after some time.
