Sci oil of wintergreen
In sci we attempted to make to make "Oil of Wintergreen" and ...... failed anyway
To start with, we added 5 ml of methanol in to a boiling tube, and added 1 ml of salicylic acid. We heated 250ish ml of water over a bunsen burner, until it was 70ish degrees. We added 3 drops of Sulfuric acid before putting the boiling tube in to the water. We let the Methanol boil off, and we got a brown liquid, not the crystals we wanted.
It instead of make little crystals we made a brown liquid like thing.
It should have looked like small little crystals.
Maybe next time we should add more or less of the ingredients.
