Question

Question 1 Use a DRY 5 mL conical vial for the reaction A Serves as a catalyst for the reaction Add one drop of concentrated phosphoric acid to the reaction mixtureTo avod splashing and evaporation of solvents while heating -8) Heat the water bath to 50 deg C Cto avoid crystals passing underneath the paper and through the filter D. So that water will fully evaporate giving a purer product Add an air condensor to the conical vial E. To avoid reaction of acetic anhydride with water F. To speed up the desired reaction, while avoiding a second reaction with a 3 moisten fiter paper with a few drops of water prior to fitration C0 making sure crystals are formed before trying to filter higher activation energy C:0 waiting overnight to take the final melting point of the product Gso that product can collect on top of crystal paper, rather than passing through the paper in the solution
