A student was given a white solid for an unknown. Its melting point range was 119-121 C. The student has previously worked with benzoic acid, and had observed that it was a white crystalline solid with a melting point of 122 C. Can the student conclude that the unknown is benzoic acid on the basis of previous work? Why or why not? What additional experimental work should be done to verify this compound?
