Recrystallization of Benzoic Acid was performed according to the method of Gilbert and Morgan (, section ). Instead of using water to recrystallize benzoic acid, ethanol was used in B part 1. The solution was also decolorized twice instead of once. Once the solution had cooled and no crystals appeared to form, 20mL of water wasFile Size: 10KB. Experiment #3: Recrystallization Experiment Date: September 20, Lab Partners: Judienne Archer Tonja Bryant Alexis Dunn Objective: To separate benzoic and acetanilide impurities by the technique recrystallization and to calculate the percent recovery of benzoic acid and acetanilide after diyqcneh.com Size: 86KB.

The solvent used for this final washing should be as cold as possible to minimize losses from the crystals re-dissolving. Both the funnel and suction flask should be chosen so that neither will become more than half full during the filtration process. The hot solution was filtered through the fluted filter paper into the heated flask.Experiment #3: Recrystallization Experiment Date: September 20, Lab Partners: Judienne Archer Tonja Bryant Alexis Dunn Objective: To separate benzoic and acetanilide impurities by the technique recrystallization and to calculate the percent recovery of benzoic acid and acetanilide after diyqcneh.com Size: 86KB. RECRYSTALLIZATION OF BENZOIC ACID Dora Shimunova 2/18/21 Professor Sara Stein Asynchronous Observations- When I saw the cold methanol alcohol and dichloromethane dissolved the benzoic acid I knew they would not be a proper solvent because a good solvent does not dissolve the solute if the solvent is cold.
