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).
