Question
Chapter 3, Problem 4Q
Interpretation Introduction
Interpretation:
The observed and the true melting point due to the rapid heating of the melting point bath should be compared.
Concept introduction:
Temperature at which an element changes from the solid state to the liquid state is known as melting point or sometimes liquefaction point. At the melting point, both solid and liquid phase coexist in equilibrium. It depends on the pressure and is normally defined at the standard pressure

A student obtained a solid product in a laboratory synthesis. To verify the identity
of the solid, she measured its melting point and found that the material melted over a
10°C range. After it had cooled, she measured the melting point of the same sample again
and found that this time the solid had a sharp melting point at the temperature that is
characteristic of the desired product. Why were the two melting points different? What
was responsible for the change in the melting point?
3. Pure benzophenone melts at 48.1°C. Your sample of benzophenone began to
freeze at 47.0°C. When you repeated this measurement, the sample again began
to freeze at 47.0°C. Give at least two reasonable explanations for this observation.
3. A student is trying to identify an unknown solid based on its melting point. She noted that the
compound began to melt at 172°C and finished melting at 177°C. Knowing it is possible for there
to be impurities in the sample, is this compound more likely to be camphor or hydroquinone.
Explain your reasoning.
4. A young chemist has synthesized what he believed to be acetaminophen. He measured the
melting point of this newly formed compound to be 163-178°C. If the literature value for the
melting point of acetaminophen = 169-170.5°C, would the young chemist be wise to consume
this product for headache relief? Why or why not?

- Due to the fact that the liquid you used was a volatile one, it will not completely recondense. Some of the liquid remains in the vapor phase, even at room temperature. If you were able to correct for this by making the vapors recondense completely, would your final molar mass value be greater than, less than or the same as the value you determined? Explain your reasoning.arrow_forward9)Who measures melting points?arrow_forward4. When performing a melting point on a solid compound using a melting point apparatus, two melting point determinations were made. One sample, which was 1 mm in height in the capillary, possessed a melting point of 200.0-200.5°C. The other sample was 25 mm in height. What would you expect the approximate melting point to be for this sample, assuming identical heating rates of 1°/min? (Hint: heat is applied from the bottom of the sample) (Give an actual numerical approximation!) 5. For the same solid compound as the question above, if the 1 mm sample was heated at 60° per minute on a melting point apparatus, what would you expect for an approximate melting point? (note that at this heating rate, the sample will melt rather quickly, but again give an actual numerical approximation)arrow_forward

An organic student did an experiment extracting benzoic acid from a mixture of other organic substances. Other analyses of the obtained sample confirmed the presence of benzoic acid. The student also measured the melting point of the white solid, 117.4-121.6 oC. The literature mp of benzoic acid is 122.3oC. What can you conclude about the sample? Select one. Group of answer choices The sample of benzoic acid contains soluble impurities. The student obtained a good yield of benzoic acid. The sample of benzoic acid contains insoluble impurities. The student obtained pure benzoic acid from the extraction. The student obtained a poor yield of benzoic acid. 2. Which phenomenon are sometimes confused with melting during mp analysis?

Can you still measure the melting point? If so, how? 7. We should not re-use a sample in a capillary tube for melting point measurement. Why not? 8. It takes significant amount of time for the melting point apparatus to cool down before next measurement if your new sample has a lower melting point than your previous one.
