First, make sure that the calorimeter, the stirring rod, and
the thermometer or thermal probe are clean and dry. Do not use
an organic solvent (such as acetone) to dry the calorimeter, as
organic solvents may dissolve the Styrofoam.
After assembling the calorimeter as described in the video, and before
beginning the experiment, make sure that:
the lid fits tightly
there is a way to measure the temperature of the reaction mixture
there is a way to mix the reaction mixture.
the thermometer or probe is secured with either a clamp or rubber band in a position above the stirring mechanism. Failure to position the thermometer correctly could lead to inefficient stirring, or worse yet, a broken thermometer!
