Compound
Above are examples of compound substances.
Mixture
A mixture contains two or more substances that are not chemically combined.
Homogeneous
A substance can be defined as homogeneous if it contains only one kind of compound or one element. Here are some examples.
Solutions
Mixture of a solid and a liquid where the solid never settles out, eg saltwater
Heterogeneous
of or denoting a process involving substances in different phases (solid, liquid, or gaseous).
Suspension
A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase some time after their introduction.
We apply the word 'suspension' when particles are big enough to eventually settle. If the particles are too small to ever settle, they are said to form a colloid.
We use the terms 'solute-like' and 'solvent-like,' because we are dealing with a heterogeneous mixture, while the terms solute and solvent refer to solutions, which are homogeneous.
Colloid
A heterogeneous mixture in which solute-like particles do not settle out.
Above is a video to help you understand the difference between solutions, suspensions, and colloids.
