A 500.0 μL aliquot of a ferric chloride solution is added to a 50.00 mL volumetricflask. To this flask is added 10 mL of 2M sodium acetate, 2 mL of 10 wt%NH4OCI, 3 mL of 5 wt% 1,10-phenanthroline, and enough DI water to fill theremaining volume of the flask for a total volume of 50.00 mL.Based on the UV-Visible light absorbance, the concentration of [Fe2+]=2.6 ppm.What is the concentration of Fe3+ ion in the original ferric chloride solution?O 3.85 X 103 ppmO 260.0 ppmO 260 ppmO 130 ppm

The concentration of Fe3+ in the original ferric chloride solution can be calculated as follows:…

DAY 1 Preparation of Aspirin Using tap water, set up a boiling water bath in a 400ml beaker. Residual solubility. The solubility of acetylsalicylic acid is 0.25 g per 100 ml of water. Keep track of how much DI water is added to the aspirin during filtration and recrystallization. Mix the starting materials and heat. Using the electronic balance, weigh about 2 g (± 0.01 g) of salicylic acid (caution: this is a skin irritant) in a 125 – ml Erlenmeyer flask. Cover the crystals with 4 – 5 ml of acetic anhydride. (caution: acetic anhydride is a severe eye irritant --- avoid skin and eye contact). Swirl this reaction flask to wet the salicylic acid crystals. Add 5 drops of conc H2SO4 to the mixture and gently heat the reaction flask in a hot water bath (60-70oC) for 5 – 10 minutes. (caution: H2SO4 causes severe skin burns). Set up an ice water bath in a 250ml beaker. Cool to crystallize the aspirin. Remove the reaction flask from the hot water bath and add 10 ml of deionized ice…

A pipet is used to transfer 5.00 mL of a 1.25 M stock solution in flask “S” to a 25.00-mL volumetric flask “B,” which is then diluted with DI H2O to the calibration mark. The solution is thoroughly mixed. Next, 3.00 mL of the solution in volumetric flask “A” is transferred by pipet to a 50.00-mL volumetric flask “B” and then diluted with DI H2O to the calibration mark. Calculate the molarity of the solution in volumetric flask “B.”
