1) During a melting point determination, the heating is constant and causes the temperature of the unit to continuously rise. In light of that, explain in your words why a measured melting point can never truly be a single temperature. Which would give a smaller melting point range, slower heating or more rapid heating? A small sample or a large sample? Explain.

2) Explain why it is common practice to determine a melting point on an unknown compound rapidly first, and then to rerun the melting point slowly.
3) This lab uses a mixed solvent system. Explain the possible advantages of using two solvents and the properties of those solvents that are important. Don't look up the answers, think.
4) If fine sand were an impurity in a sample, how would it affect the melting point? What would make you suspicious that something inert like sand was contaminating your sample?
