A student thinks they may have one of two possible compounds. Compound A, has a melting point of 160°C, compound B has a melting point of 161°C. The student’s unknown melts at 160.5°C.
The student test the unknown again and gets 160.4°C…160.6°C. How can students use compound A or B to determine the identity of the unknown?
