**Transcription for Educational Website**---**Question 4: Understanding the Melting Point of an Impure Sample**A student received an impure sample of benzoic acid and reported the melting point as "mp = 121.5 °C." The student reported the sample as pure since the melting point wasn't too far off. What mistake was made that could have proven the sample’s impurity?---This text focuses on a common laboratory scenario where correct identification of sample purity is crucial. It highlights the importance of understanding how melting points can be affected by impurities and encourages critical evaluation of experimental results. For more educational content on chemical purity and melting point analysis, refer to our resources on laboratory techniques and error analysis.

The mistake made by the student that could have proven the sample's impurity is not comparing the…
