Hello and Thanks from Now, the question is We have a compound with a melting point of 134C we suspect that is aspirin 135C or Urea 133C. Explain how we could determine if one of these suspects urea or aspirin is identical to the first with the 134C.
Homework Answers
The compound is Urea.
Generally if any compound is mixed with impurities, its melting point generally increases.
Urea compound has melting point of 1330C if it has impurity its melting point is slightly increases from 1330C to 1340C.
