You have a solution of the three molecules below in a suitable organic solvent. NH₂ OH In addition to the organic solvent and the three molecules, you have access to the following solutions: 1 M NaOH 1 M HCI 1 M CH3COOH 1 M Na2HPO4 Outline a method for how you would separate this solution into its component parts and briefly explain your rationale. You do not need to provide the level of detail shown in the Experimental; just the basics will be sufficient (e.g. wash with ______ to separate component_____, then wash with to separate component Y, etc.). Hint: you might need to search their pką values! You can write in paragraph style or organize your steps in a numbered list.

The chemical 5-amino-2,3-dihydro-1,4- phthalazinedione, better known as luminol, is used by forensic scientists in analyzing crime scenes for the presence of washed-away blood. Luminol is so sensitive that it can detect blood that has been diluted 10,000 times. A basic solution of luminol is often sprayed onto surfaces that are suspected of containing minute amounts of blood. Luminol has a molecular weight of 177 g/mol. The forensic technician at a crime scene has just prepared a luminol stock solution by adding 17.0 g of luminol into a total volume of 75.0 mL of H₂O. What is the molarity of the stock solution of luminol? Express your answer with the appropriate units. ► View Available Hint(s) molarity of luminol solution = 1.28 M Submit Correct Part B Previous Answers Before investigating the scene, the technician must dilute the luminol solution to a concentration of 4.00 × 10-2 M. The diluted solution is then placed in a spray bottle for application on the desired surfaces. How many…
All of the solutions used are nominally 0.1 M. However, they are not all exactly the same concentration-recognize that these labels show only 1 significant figure. List the four reagents used (HCI, NaOH, acetic acid, and NH3) in order of increasing concentration, e.g. w <x<y<z, or w <x< y <z, etc. Make sure to justify your ranking. Please note that this has nothing to do with degree of dissociation.
You have already dissolved the reagent in distilled water, although the pH is less than the target pH. What accounts for this discrepancy in pH?
please round the answer to 2 decimal places
Consider a buffer solution prepared by adding 0.45 mol of CH3COOK to 1.00 L of 2.00 M CH3COOH. (K₁ = 1.8 x 10-5). If 0.05 mol of HCI is added to this buffer solution the pH of the solution will drop slightly. The pH does not drastically decrease because the HCI reacts with present in the buffer solution. Select one: O a. H₂O O b. CH3COOH O C. CH3COO O d. H+
