UAEU College of Science Department of Chemistry Organic Chemistry Laboratory I (CHEM 245) Report (1) Recrystallization of acetanilide Initial Melting Final Melting Compound Weight (g) Temp. C Melting Range Temp. C Crude Acetanilide 3.1 108 114 Pure Acetanilide 114 116 Weight of (watch glass + filter paper) - 43.71 g Weight of (watch glass + filter paper + precipitate) = 45.58 g 1- Based on data provided in this experiment, Calculate acetanilide % recovery? 2. Calculate the % error for the melting point of the purified acetanilide. 3. Based on your obtained data, indicate whether you acquired more purified acetanilide or not? Why? (Hint: Sharp M.P range means pure sample, Broad M.P range means impure sample) 4- Suppose you did not get crystals during this experiment, Answer the following: a) In which step are you? b) In your opinion, What's the reason for that? c) How could overcome that
