Materials Lab Quest Temperature probe Two test tubes 400ml beaker and 100 ml beaker Ring stand and hot plate Utility clamp Methods First step is to obtain and wear all safety gear. Set up the heat plate with the 400ml beaker with water inside. Obtain the two test tubes with the acids in them and place them in side the water beaker on the hot plate. Turn on the hot plate and allow for acid to melt on steady heat, do not turn up heat on high the water will start boiling and splashing out of the beaker and may cause burns. As the water is heating on the plate and the acid is melting, start setting up the lab quest and connect temperature probe and calibrate it to make sure its accurate. Set up another 100ml beaker with room temp water. Once the lauric acid is completely melted in the test tube in the hot water bath, insert the temperature probe into the tube and transfer the test tube into the room temperature beaker and observe the temperature change on the LabQuest and record data. Very gently stir the acid until completely solid. Once the acid solidifies place back in hot water bath to melt and retrieve the probe. Clean the probe and repeat same procedure for the lauric-benzoic acid solution and save results. Print all graphs obtained from LabQuest and include in the results.
