Experimental Procedure for Part C: Add approximately 2-3 drops of each pair of reactants in the first column to a test tube. Use 0.1 M solutions for all reactants except when noted differently. Record your observations in column Experimental Observations. Be sure to note the formation of a precipitate, any color change, color of precipitate, evolution of a gas, etc. For a "b" reaction, add 6 drops of the indicated reagent to the precipitate that is left in the well plate to determine if it dissolves. Record your observations in your notebook. Table III: Double Displacement Reactions Reactants Experimental Observations la Ba(NO:)2(aq) + K2SO4(aq) Do not write here.

Experiment 2 - Extraction Procedure The procedure[1] has been outlined below. Add details if needed so that you are able to complete the experiment in lab using only this document. The following chemicals may be encountered during this experiment: Acetylsalicylic acid Sucrose Acetanilide Ethyl acetate Sodium bicarbonate (NaHCO3) Hydrochloric acid (HCl) Sodium sulfate (anhydrous) Dissolve phensuprin (0.5 g) in ethyl acetate (25 mL). Measure out 0.5-1.0 g of phensuprin and put it in a beaker (100 mL) along with 25 mL of ethyl acetate. Stir for 1-3 min, breaking up any chunks as needed Sucrose will not dissolve, but everything else will. Gravity filter the solution to collect the sucrose. Set up a glass funnel in a ring or clamp, so that it will drain into a clean Erlenmeyer flask (125 mL). Put a fluted filter paper into the funnel and "wet" it with ethyl acetate. Optional: Weigh the filter paper before using it. Swirl and pour the solution into the funnel, being…

Can you answer this question please: Explain why bromoethane was added last (Please type your answer) 1.063 g of p-acetamidophenol was measured out into a 50 mL round bottom flask along with 8 mL of 1M NaOH in ethanol and a stir bar. This mixture was heated at reflux for 15 min. It was allowed to cool and then 0.80 mL of bromoethane was added to the reaction. The mixture was then heated at reflux for another 15 min. After heating, the solution was poured onto a mixture of ice and water and further cooled on ice and then the solid was collected by vacuum filtration. This solid was then recrystallized from ethanol and water. The final mass of the purified phenacetin was 0.42250 g

Inside a 125-mL Erlenmeyer flask, add 6.1 mL of methyl benzoate, and 12mL of sulfuric acid. Place this flask into an ice bath. In a separate flask, add 4mL of sulfuric acid and 4mL of nitric acid; place this flask into an ice bath. Using a pipette, transfer the mixture of flask #2, into the original flask, (#1). Allow the reaction mixture to warm up to room temperature and wait 15 minutes. After, pour the mixture into a 100mL beaker, filled with 50g of ice. Prepare a vacuum filiation. Pour the reaction, then first wash with cold water, and then wash with 10mL of cold methanol twice. weight the product and Save it to be analyzed by melting point .
