Benzene is aromatic because it has alternating double bonds between each carbon. Pages 40 This preview shows page 21 - 27 out of 40 pages. On the following picture you can see that a precipitate has formed, after the addition of the Hydrochloric Acid. Your complete report for this experiment should include the data page, answers to the following questions, and a conclusion (1 page maximum. Heat the mixture with magnetic stir My Kitasato (also known as Buchner Flask, Vacuum Flask or Filter Flask) was KIA (killed in action). Potassium Benzoate is quite soluble in water. The oxidation of toluene forms benzaldehyde which can further be oxidized to form benzoic acid. Allow the collected solid to air dry in an open container until the beginning of next lab.9. WebThe accoster is taking a substance. WebThis experiment is about extraction of benzoic acid from kerosene by water droplets that was conducted on 6 October 2015 with few group of students. WebBenzoic Acid Lab Report. In Experiment Two we will be recrystallizing Benzoic Acid using a solvent pair made up of Methanol and Water. When toluene is refluxed with alkaline KMnO4 solution (aqueous KMnO4 + Na2CO3), it is oxidised to benzoic acid. Production of phenol involves the use of benzoic acid. 121.1,2.
