You are given a sample which is either pure benzoic acid (melting point= 122.5 C) or pure 2-naphthol (mp=123 C). Using what you know about how melting point helps determine whether a sample is pure, describe an experiment which will identify the unknown solute. You should explain how specific observations from this experiment would support the chosen identity.
