Part 2: Identification of a solid sample You have a solid unknown which you think could be benzoin (m. p. 135-137°C), trans-cinnamic acid (m. p. 133-134°C), or urea (m. p. 132-134°C). You are provided with pure samples of these compounds and the unknown, along with a pestle and mortar, capillary tubes, and a melting point apparatus. Devise and carry out experiments to determine which one of these compounds is your unknown. In your notebook, record your experimental plan, clearly and fully, then document all your results, and state a conclusion about the identity of your unknown compound.
