Determination of Mass and Mole Relationships AP Chemistry Kit

carolina
Meets AP® Chemistry experiment 9. Students use the method of continuous variation to determine the stoichiometry of 2 acid-base reactions. Whereas most stoichiometry experiments rely on precipitation reactions, this procedure uses temperature change to determine the correct stoichiometry. As a result, the experiment generates less waste and, because it uses only dilute acids and bases, is safer than traditional procedures. It is possible to do 2 trials in one 50-minute class period.

Materials are sufficient for 30 students working in groups of 3.
