A solution is a homogeneous mixture where the solute is completely dissolved, while a suspension is a heterogeneous mixture where particles are suspended but not dissolved. Example: Muddy water is a suspension.

Front

What is an example of a heterogeneous mixture?

Back

An example of a heterogeneous mixture is a fruit salad, where the different fruits can be seen and separated.
