1. CONCENTRATION UNITS
1. CONCENTRATION UNITSA solution is a homogeneous mixture of two or more chemical substances. If we have a solutionmade from a solid and a liquid, we say that the solid is dissolved in the liquid and we call thesolid the solute and the liquid the solvent. Initially, we will consider only solutions of a solid inwater. If a solution has a small amount of solute in a large amount of solvent, we say that thesolution is dilute (or that we have a dilute solution). If a solution has a large amount of solutefor a certain amount of solvent, we say that the solution is concentrated (or that we have aconcentrated solution). We see that the terms dilute and concentrated are not precise and aremerely used to give a rough indication of the amount of solute for a given amount of amount of solute in a given amount of solvent (or solution) is called the CONCENTRATION ofthe solution. In this course, we will consider two ways of expressing CONCENTRATION - masspercent and molarity.
