Why is it not good practice to mix two components by simply stirring them together and then
  sampling them forStirring two solid components together does not yield a homogenous mixture but a coarse
  mixture of particles, lumps, and crystal of the individual compounds. A small sample for a
  melting-point determination taken from the coarse mixture might be 100 of one component.
   a mixed melting point?

Question 2

Look up the melting points of the following compounds in a suitable handbook, Internet site,
  or online source. (See Technique 17, p. 198.) Include the name of your source with your
  answer.
  (a) Quinine
  (b) Indophenol
