    im not sure how to answer the questions.

    I think the first one wants you to discuss IF melting points can be used to determine purity and if so, then how. I would think a discussion of the melting point range would be useful (what range indicates high purity and what range indicates low purity) as well as something about mixed melting points, how they are used, and what they mean with regard to purity. In addition something needs to be in the discussion that the melting point may indicate the purity BUT it doesn't tell you what any impurities are in the sample.

    For #2, I think the discussion is to centered around the difference between indicating PURITY and indicating the IDENTITY. Particularly, I think the discussion should include using (or not using) the melting point of a sample to identify the sample beyond a reasonable doubt versus using derivatives and reactions of a sample to indicate the identity.
