Colloids, Suspension, and Solution

Front

What is a colloid?

Back

A colloid is a mixture where tiny particles are dispersed throughout a medium but do not settle out.

Front

What is a suspension?

Back

A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase over time.

Front

What is a solution?

Back

A solution is a homogeneous mixture composed of two or more substances.

Front

What is the main difference between a colloid and a suspension?

Back

The main difference is that in a colloid, the particles do not settle out, while in a suspension, they do.

Front

What is the particle size range in colloids?

Back

The particle size in colloids typically ranges from 1 nanometer to 1 micrometer.

Front

What is the particle size range in suspensions?

Back

The particle size in suspensions is larger than 1 micrometer.

Front

What is the particle size range in solutions?

Back

The particle size in solutions is less than 1 nanometer.
