Decent Essays

To begin the lab, two dry and clean 125ml Erlenmeyer flasks are weighed separately on a top loading balance with a piece of 2.5” x 2.5” aluminum foil and an elastic band. After weighing, 2ml of the unknown organic liquid sample is poured into each of the Erlenmeyer flasks and secured with the aluminum foil that is wrapped around the mouth of the flask and secured with the elastic band. After the smaller set of aluminum foil has been secured, the larger pieces of aluminum foil, 3.5” x 3.5”, is then secured with an elastic band over the previously secured aluminum foil. Two water baths are placed on hot plates in 600ml beakers filled up to 200ml with distilled water, the stir bars are placed in the 600ml beakers and rotational speed is increased.
