Question 1

difference in melting point of pure and impure samples

Answer 1

IMPURE SAMPLE HAS A LOWER MELTING POINT THAN A PURE SAMPLE
- the melting range is the difference between the temperature at which the sample starts to melt and the temperature at which melting is complete. If the compound contains impurities the solid melts over a wide range of temperatures, whereas a pure organic substance usually has a very sharp melting range of one or two degrees
