Answer:

A solution is a homogeneous mixture of two or more chemical substances. If we have a solution

made from a solid and a liquid, we say that the solid is dissolved in the liquid and we call the

solid the solute and the liquid the solvent. Initially, we will consider only solutions of a solid in

water. If a solution has a small amount of solute in a large amount of solvent, we say that the

solution is dilute (or that we have a dilute solution). If a solution has a large amount of solute

for a certain amount of solvent, we say that the solution is concentrated (or that we have a

concentrated solution). We see that the terms dilute and concentrated are not precise and are

merely used to give a rough indication of the amount of solute for a given amount of solvent.

The amount of solute in a given amount of solvent (or solution) is called the concentration of

the solution. In this course, we will consider two ways of expressing concentration - mass

percent and molarity. We will consider molarity here and mass percent later.
