Abstract The main purpose of this experiment was to synthesize benzilic acid from benzoin. This requires a multistep synthesis with benzyl as an intermediate product. The first step required HNO3 as an oxidizing agent and the second step required KOH and HCl. The percentage yields of benzil and benzilic acid were 59.5% and 21.9% respectively. The calculated melting point of benzil was 90.1-91.6 which suggested some impurities‚ but the MP of benzilic acid was 149.3-151.5 which suggested a pure yield

the lab is to measure the mass of 250 mL beaker‚ once you have done this add .9 to 1.2 grams of aluminum can pieces to the beaker. Take the mass once again and find the difference between the two to find the mass of aluminum. Add 50 mL of a 1.4M KOH solution to the beaker. Make sure and a use a fume hood to vent the gases that are produced during the experiment. Maintain a volume of 25mL; if the volume gets low add distilled water. Next set up an aspirator to filter the reaction once it is finished

The first experiment performed was a simple acid–base titration using oxalic acid and KOH. The experiment was performed so as to check the feasibility of the idea behind the development of automated system for the measurement of pH and to have enough confidence in performing future experiments and also to check the response of the interface
