Question

Please help with question 3. Thank you!
Disposal of waste: When necessary, all organic waste must be disposed into the organic waste container, all aqueous waste to the aqueous waste container and all solid waste to the solid waste container. Nothing is disposed in the sink or trash can. Synthesis of acetanilide In a dry small conical vial, dissolve 300 mg (or 30 drops) of freshly distilled aniline in 1.0 mL of 1.0 M hydrochloric acid. Swirl the mixture to hasten the dissolution. Label this solution as “Solution A”. Dissolve 480 mg of sodium acetate trihydrate in 0.9 mL water and label this as “Solution B”. Warm “Solution A” to 50 °C on a hot plate at a low setting. As soon as the temperature is attained, remove the solution from heat and immediately add 360 uL of acetic anhydride. Swirl the vial well. Immediately add “Solution B” in one portion and cool the reaction mixture in an ice bath to 5 °C. (Note: on a larger scale, exercise caution when adding water to the reaction mixture because the exothermic hydrolysis of acetic anhydride is slow at room temperature but can get out of control at higher temperatures). Collect the crystals by suction filtration and let the crystals dry thoroughly on the Buchner funnel. Then transfer the crystals to the folds of a filter paper and roll a beaker over till the paper is no longer wet. Once dry, determine the weight, calculate the percent yield, and determine the melting point. Bigpeak is DMSO To8-110 0.2159 651 Synthesis of p-bromoacetanilide Start - low concentration you To a 10 mL round bottom vial equipped with a magnetic stir bar, add 0.25 gacetanilide,
