Please type all of the parts to this question occordingly to the instructions. Here is an example of a formal procedure based off of the experiment presented in Mohrig:Sodium hydroxide (4.6 g) was dissolved in water (25 mL). This solution was added to a 100 mL round bottom flask along with methyl salicylate (2.0 mL) and a stir bar. The mixture was heated at reflux for 15 min and then progressively cooled to 5 °C. The solution was acidified with 3M sulfuric acid (15-20 mL), and the resulting solid was collected by vacuum filtration. The crude salicylic acid was recrystallized from water to yield ???? g of final solid. The melting point and IR were taken to assess purity. Calculate the molarity of the solution of sodium hydroxide that is used.a. M = b. If the original procedure is the base scale (100%), how far are we scaling down the reaction when using 0.75 mL of methyl salicylate? (Example: the original uses 2.0 mL, if we were to use 1.0 mL, we would be scaling the reaction down…
If the reaction mixture containing p-aminophenol, distilled H2O, and acetic anhydride was heated to 200 degrees celsius what would have happened? (For my Acetaminophen lab. Originally I was instructed to heat to 100 degrees celsius instead for 10 mins to dissolve and crystallize)
Find the Ksp of distilled water with Mg(OH)2 as its salt (solubility:1.51121E-05 M) MgCO3 as its salt (solubility: 1.78E-06 M)
Considering the procedure below: “Determination of the concentration of HCl: Pipette 10 mL of hydrochloric acid and transfer to a 100 mL volumetric flask, complete the volume with water and homogenize. Remove a 10 mL aliquot of this solution and transfer it to a second dilution in a 100 mL volumetric flask, complete the volume with water and homogenize. Take a 20 mL aliquot of this last solution and transfer to a 250 mL erlenmeyr and add 20 mL of distilled water and 4 drops of the acid-base indicator. Titrate with a previously standardized 0.100 mol/L sodium hydroxide solution until the indicator turns.” Answer: a) In this titration, the indicator used is phenolphthalein. Discuss the use of this indicator considering its turning range and pH at the stoichiometric point of the titration. Justify. b) Considering that the volume of titrant used was equal to 24.5 mL, calculate the concentration of HCl in the sample in mol/L.
Provide a mechanism, including intermediates, for the following procedure Charge a 100 mL round-bottom flask with 40mL of 2 M pentanolic KOH solution, 5.0g of PET shavings, and a stirring bar. Heat the mixture to a gentle reflux and keep it refluxing for 2 hours with continuous stirring. Cool the reaction mixture and add 25 mL of water to dissolve the white terephthalate salt. Filter the solution using a Büchner funnel to remove undissolved PET. Transfer the filtrate to a separatory funnel and remove the bottom aqueous layer. Wash the pentanolic layer with an additional 25 mL of water, remove the bottom layer, and combine with the other aqueous layers. Add 2 M HCl to the aqueous layer while stirring until a precipitate that does not dissolve forms. Add the same volume of HCl again (approximately 30 mL or more) to fully protonate the compound. Collect the solid by suction filtration and air-dry it to obtain 4.138 g with a melting point above 400 °C. Set aside 0.5-1 g of the sample for…

1,4‐Dimethoxybenzene (0.642 g) was dissolved in 2.0 mL acetic acid in a 25 mL Erlenmeyer flask using heat from a hot plate. Once the solid dissolved, 1.0 mL tert‐ butanol was added, and the reaction mixture was cooled in an ice bath. Then 2.0 mL concentrated sulfuric acid was added in 2‐3 drop portions,stirring the mixture after each aliquot. After the addition, the flask was removed from the ice bath and allowed to sit at room temperature for 15 minutes. Then 1.0 mL water was added dropwise to dilute the acid and the reaction mixture was added to 40 mL cold water in a 100 mL beaker. The solid was vacuum filtered and washed with 5 mL cold water, giving 52 g filtrate. The product wasrecrystallized from 4.5 mL methanol, yielding 0.317 g purified 1,4‐di‐tert‐butyl‐2,5‐dimethoxy benzene (27.2% yield). What is the atom economy, e-factor, and effective mass yield?
