Complete the following exercises in the spaces provided:
1.
Describe the effects of impurities on the melting point of a pure substance.
The presence of impurities will lower the melting point and wwiden the range
2.
Based on your experience with this simulated experiment, what is a reasonable definition of a
pure substance.
pure Substance is a Substarce having narrow rarge of melting pint
An unknown solid has a melting point of 132-135°C. A mixed melting point of the unknown with
3.
urea, gives a melting point of 120-126°C. Based on your understanding of the effects of impurities on
melting points, is the unknown urea or not? Briefly explain your answer,
compound is ot urea becousf, if the in knoon campound is uea, it will giue Same
and
range as urea. Here urea acts s an imperityto the
meHing Point
An unknown solid has a melting point of 112-114°C, Based on data from Table 1 above and
4.
the mixed melting point technique of this experiment, you can narrow down the possibilities to three
compounds. List the compounds.
me possible compords are 3-toluic acid, acetanilide,4-hydroxyacetanilide
A mixed melting point of the unknown with acetanilide gives a melting point of 113-114°C Is
the unknown acetanilide or not? Briefly explain your answer.
The anknown is acetanilide, the unlcnown gives the same
