In this experiment, the percent recovery values were 14.2% and 59.7%. The lower percent recovery means that only a small amount of crystals were recovered. This error could be due to the fact that some of the organic compounds may have formed hydrogen bonds and therefore been soluble in water resulting in the loss of some organic compound during filtration. Another reason for such a low percent recovery could be due to the drying agent. If the drying agent is added in large amounts it could lead to losing of the organic solvent by adsorption of the organic liquid. A better experimental result would show much higher percent recovery than the ones obtained. Obtaining a 100% recovery means that nothing was lost in the process. Also, the compound could have been impure and/or contaminated and so yielding false results. One final reason for the deviation in percent recovery is also due to wrong measurements taken for the filter paper before and again with the addition of the crystals. Wrong measurements would not provide the right amount of mass for the compounds and therefore percent recovery would not be calculated
