Laboratory Equipment

identify lab equipment. In lab I learned how to test my skills for accuracy I know how to do this in that when weighing objects the closer you were to the actual weight the more accurate you were. In lab I also learned what the safety rules are some examples of the safety rules are safety goggles should be worn at all times, when mixing water and acid mix acid into water and always turn the burner off when it is not in use. In lab I also learned how to able and identify lab equipment some examples...

Benzoic Acid

probably insoluble in the hot solvent and will be separated from the hot solution by gravity filtration. If there is any such insoluble solid residue, gravity filter this hot solution through a fluted filter paper using the apparatus shown in your laboratory textbook. Since the glass funnel you have used is much cooler than the hot solution, cooling of the solution will occur, resulting in some crystallization of the benzoic acid in the stem of the funnel and in the filter paper. Preheating the funnel...
