Chem341:Recrystallization experiment

lase 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.

First you will need to create an account, as described here. To edit this page, click on the "edit" tab, make the necessary changes, then click "Save page". If you want to check that your edits are right before you save, then click "Preview" instead (I usually do this).

When adding data to the table, 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).
