RTY Uno Collect the recrystallized product by vacuum filtration with the clamped Hirsch funnel and wash the crystals with 1 mL of cold, 50% aqueous ethanol. Then allow the crystals to air dry until the next laboratory period. Percent Yield and Characterization Weigh the dry product and calculate a percent yield. Then determine its melting point range and compare the result with the literature value. Submit the product in a labeled plastic bag with the report Questions 1. Use the...

Name Lab Partner LAB 9 REFLECTIVE EXERCISES Lab Section 1 What data did you collect to indicate that you successfully produced aspirin? What did your results indicate about the purity of the aspirin you obtained? Explain your answers. 2 Given that the melting point of salicylic acid is 159 C, can you be certain that the product you isolated was not pure solicylic acid that was unchanged during the reaction? Can you be certain that the product you isolated was...

Imagine these two products are dissolved in CH2Cl2. The solution
is treated with 2-propanol/HCl until pH is approximately 7,
resulting in the formation of crystals. The crystals are isolated
using vacuum filtration. The sequence of actions described above
results in the separation of the two products A and B. Why? How?
