Stoichiometry is worth 40% of the chemistry 20 curriculum, as it relates to all units. The reason I teach this unit last, is due to the fact that, after learning everything else, stoichiometry just makes sense. Basically, the chem 20s have most of the knowledge required to understand the stoichiometric process, and its just a matter of putting it together! Exciting!
This week in chem 20, the students will be learning about titration techniques, and we will be performing our first (mini) titration. TItration is a quantitative stoichiometric lab technique that is used in many chemical industries today. The purpose of titration is to determine the concentration of an unknown, using the known concentration and volume of another reactant in a chemical reaction. This technique is key to success in chemistry 20 and used often in chem 30. Additionally, there is an entire chemistry section (ANALYTICAL CHEMISTRY) dedicated to this process. So needless to say, titration is important!
