Description: while you would like to have a large recovery of your solid if you dont know how much impurity is present then you cant necessarily judge your success only by that result but regardless of h 17116

While you would like to have a large % recovery of your solid, if you don't know how much impurity is present, then you can't necessarily judge your success only by that result. But regardless of how much you obtain, your sample must be pure. Based on all the data you've collected, convince me that your sample is pure acetanilide.

Weight of acetanilide used = 5.0235 g Weight of purified acetanilide obtained = 3.7528 g Melting point of purified acetanilide = 114-115 °C Your task: 1) Calculate the % yield 2) What does the recorded melting point tell you about the purity of the acetanilide? 3) What is the melting point of the impure acetanilide expected to be? 4) Does rate of cooling of the heated acetanilde solution affect the purity of the product obtained? Explain why or why not. 5) What properties are required of a good solvent for recrystallizing a compound? 6) Could hexane, a non-polar solvent, be used instead of water in this experiment? Explain the reason for your answer. 7) The structure of acetanilde is shown below. Use ARIO to Rank the relative acidities of three types of Hydrogen (consider all the Hs on aromatic ring to be same type and acidity). Explain the reason(s) underling your ranking 8) How can you use recrystallization in another specific application (as per question in template)
