The number of moles of NaOH is 0.5 . Calculate the moles of methyl salicylate reacted ( use density :1.17 g/mol Part 1: Preparation of reaction mixture1. Add 2 x 20 cm3 of the 20% NaOH solution to the 250 cm3 round-bottom flask. Usea funnel to prevent the neck of the flask from getting wet.2. Use another clean funnel to add 3 cm3 of methyl salicylate to the solution in theflask.3. Add a pinch of boiling chips to the mixture.4. Make sure that the neck of the flask is clean and dry before lightly greasing theneck with tap grease.5. Assemble the apparatus for reflux (see figure below).water outletLiebig condenserwater inletclampsreaction flaskretort standblue flamemetal standbunsen burner cical Manual_Praktika Handleiding_2021.pdf28 / 86136%Part 2: Reflux reaction6. Open the tap and ensure that the Liebig condenser is completely filled with runningwater. The piping and water will be already switched on using the water savingsystem. Ensure that the pipes are handled with care as water can easily leak out.7. Light the Bunsen burner and place it + 2 cm below the round-bottom flask to heatthe solution.8. Boil the mixture under reflux for 30 minutes.9. Extinguish the flame and allow the flask and its contents to cool to roomtemperature.10. Quantitatively transfer the reaction mixture to a 250 cm3 glass beaker.Work-up of product11.Acidify the reaction mixture by adding 3 M H2SO4 (approximately +5 cm3 at a time).Use Congo red paper to determine when the mixture is acidic.12.After confirming that the reaction mixture is acidic add a further 15 cm3 of H2S04.13.Place the beaker in an ice bath (a larger beaker containing ice and water) to cooldown the mixture. A white precipitate should form as your final product.26
