In this lab experience, students carry out an investigation to determine how a mole can be used to describe solution concentrations. Students come to understand that as the amount of solute dissolved in a fixed amount of solvent increases, solution concentration as described by the quantity, molarity, also increases. Students learn that in colorful solutions it is easy to differentiate based on concentration. Students learn about the mole-based calculation needed to prepare solutions, and also about the appropriate procedures and glassware for preparing solutions with accurate concentrations.
