Answer to Part-B: The melting point of benzocaine is 88–90 °C. And experimental observation is 75-80 °C. The product was not pure. Because if the product was pure, it melts sharply at 88–90 °C. 10 °C difference is too big in terms of purity.
Answer to Part-C: In the laboratory, anhydrous sodium sulfate is widely used as an inert drying agent, for removing traces of water from organic solutions. It is more efficient but slower-acting than the similar agent magnesium sulfate.
Hope you like the answer.
can you help with part b why isn't the product pure based on the melting point???...

Question 14 The melting point of a pure compound is known to be 110-111º. Describe the melting behavior expected if this compound is contaminated with 5% of an impurity. 90-96 111-113 90-91 110-111 5 pts Question 15 You and your lab partner take melting points of the same sample. You observe a melting point of 101-107°C, while your partner observes a value of 110-112°C. Explain how you can get two different values with exactly the same sample. One of the...
