Please record data (%recovery, MP)below for the recrystallization experiment. If students report that they had a lot of oil, and they had to decant their solution into another flask (this happened a lot with the Tuesday section), don't include those data here. Instead, just record the data on a piece of paper so we can look at them separately.
The |- symbol indicates a new line of data, then the data are entered after the | symbols (first %recovery, then MP). On the first line I have put in some example data - 77%, and a MP of 113-114 °C for acetanilide (other compounds have a different MP).
Acetanilide
Table 1: Acetanilide results % Recovery MP 77 113-114
Salicylic acid
Table 2: Salicylic acid results % Recovery MP 77 157-159
m-Anisic acid
Table 3: m-Anisic acid results % Recovery MP 77 101-103
