PROCEDURES: A) Preparation of three Standard ASA solutions. 1) These solutions will be prepared using a stock solution of ASA-Fe, the concentration of ASA- Fe stock is precisely known. The intensity of the purple color is an indication of the amount of ASA-Fe present in the solution. The darkest one should be the highest ASA concentration. 2) Clean three 25mL volumetric flask by washing with soap and water (fill 4 full and swirl several times), rinsing with tap water (4 full and swirl, repeat 3 times) and rinsing with deionized water (4 full and swirl, repeat 3 times). Be sure to drain all water from the flask by shaking it several times to expel the water. 3) Label the three 25 mL volumetric flasks standard A, B, and C, respectively. 4) Prepare your three standards by pipetting 1.00 mL, 2.00 mL and 5.00 mL of the stock 0.0028M ASA solution into the flasks labeled A, B, and C, respectively. Now fill the the flask to the volumetric line with iron(III) chloride solution. Note: Be careful not to overfill the volumetric flask or you will need to start again. Use a disposable pipet to finish filling the flasks until the meniscus is at the bottom of the scribed line 5) Determine and record the molarity of each of the three solutions in your lab manual using the standard dilution formula: Minitial Vinitial = Mfinal Vfinal
