- 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…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.B. Organic Derivatives of Water Five organic derivatives of water were analyzed by various qualitative tests and the summary of their reactions is given in Table 2 below. Identify each unknown sample by matching the respective reaction profile with the given structures (A, B, C, D or E). Table 2.

- Each of the student statements below is wrong. Explain why they are not correct. (a) All my compound dissolved right away in the small amount of solvent I added at room temperature, and I didn’t need to heat it at all. This means I’m going to get lots of pure compound out. (b) I did a recrystallization of naphthalene and my percent recovery was very high (99%), so I must have pure product. (c) When you’ve dissolved all your compound in hot solvent, and you’re in a hurry, it’s ok to just place it straight into the ice bath.Give an example of an antimicrobial pro-drug that was developed so it doesn’t absorb in the gastrointestinal tract.

- Nina, Roland, and Odi tried to do a recrystallization technique to purify a crude sample of benzoic acid. However, their instructor, George, pointed out some things about their technique. Roland forgot to add charcoal to the crude sample. Nina put the hot sample in the ice bath immediately. Odi used a long-stemmed funnel. Who among the students will achieve the highest purity? a. None of the above b. Nina c. Odi d. Roland Explain why.

Make sure to indicate the phaseof each chemical in every step (s, l, g, aq) and write the separation technique used in eachstep (ie: vacuum filtration). The list below gives the reagents available in the lab. Use anyof the reagents below to isolate the compounds. Remember that the simplest separationscheme is the best one. Try to avoid unnecessary steps. • 10% aqueous NaOH • H2O• 5% aqueous NaHCO3 • H3PO4• 6M HCl • anhydrous Na2SO4• 5% HCl • anhydrous MgSO4• Diethyl ether (ether) • Saturated NaCl• CH3OH • Sodium borohydride (NaBH4)• lithium aluminum hydride (LiAlH4) • NaCl solid
- Please answer it ASAP and CORRECTLY for an upvote. Thank you. Benzoic acid is 9 times more soluble in chloroform than in water. The percent benzoic acid that will remain from a water solution of benzoic acid if 13. Equal quantity of chloroform and water is used is 14. Twice as much chloroform as water is used is 15. If extraction as in Problem 13 were followed by an extraction as in Problem 14 isThe question is: Consider a mixture containing 0.5 benzil and 0.05 biphenyl. Your task is to isolate the benzil in pure form. Would this be best accomplished by recrystallization or extraction? I don’t really know which one would be better cause both can isolate a substance in its pure form. Thanks!It has been noticed that adulteration of palm oil with carcinogenic dyes are on the rise.
