IB Chemistry, like all Group IV IB courses, has a heavy emphasis on experimental work. This unit is essential preparation for lab work this year. We will review safety, lab equipment and measurement techniques (sig figs! uncertainty! accuracy/precision! random/systematic errors! error propagation!!) using problems that involve solution calculations. Since most of the chemistry you will do will occur in an aqueous environment (in solution) you must be comfortable calculating molarity, making solutions and dilutions. Additionally, we'll review how to use the colorimeter, providing you with the opportunity to learn how to use an extremely valuable tool for determining unknown concentrations. Using the colorimeter will also give you practice using graphs to say something about a chemical system and understanding how it works will help tremendously in how well you understand the other analytical techniques you will learn this year.
