Unformatted text preview: Results After completing the Recrystallization of the compound, we found that the melting point of our unknown compound (D) was 118ºC-120ºC. This corresponded with benzoic acid’s melting point of 122ºC. When we used benzoic acid to determine a mixed Hobbs, April Lab Results-Experiment 1 melting point, it was 119ºC-122ºC. This was less than a 5ºC difference to the melting point of our unknown. Conclusion We were able to conclude that our unknown compound (D) was benzoic acid. Our percent recovery was approximately 28.93%. Our percent recovery was not as high as we expected it to be due to splashing caused by the boiling of the solution. We tried to avoid this by adding more boiling chips and being sure to continue to swirl the solution over the heat....
