A student performs a crystallization on an impure sample of biphenyl. The sample weighs 0.5 g and contains about 5% impurity. Based on his knowledge of solubility, the student decides to use benzene as the solvent. After crystallization, the crystals are dried and the nal weight is found to be 0.02 g. Assume that all steps in the crystallization are performed correctly, there are no spills, and the student lost very little solid on any glassware or in any of the transfers. Why is the recovery so low?
You need to purify 0.8 grams of an impure sample of trans-cinnamic acid. After the purification is completed you isolate 0.57 grams of trans-cinnamic acid and record a melting point range of 129-132 °C. Cinnamic Acid has a solubility in ethanol of 13.9 g/100 ml at 10 °C and a solubility in water of 0.055 g/100 ml at 25 °C. (a) Explain why the recrystallization of trans-cinnamic acid must use a mixed solvent system. Please explain why the sample couldn't be successful recrystallized in ethanol alone. Calculations should be used to support your answer. (b) Calculate the % recovery and the % error for the melting point.

The formation of black smoke upon combustion of hydrocarbons indicates incomplete combustion which means that the sample has a [low] C to H ratio. 2. In steam distillation, the desired substance decomposes and is obtained at a temperature [higher] than its actual boiling point.
