b) In this experiment an aspirin tablet mark with deionized water. Using a pipette into a 100-mL volumetric flask and diluted to t make a 'diluted aspirin solution'. an aspirin tablet was placed in a 250-ml volumetric flask o dissolved in 10 mL of 1.0M NaOH solution, the flask was then 1.0M NaOH solution, the flask was then filled to the nized water. Using a pipette, 5.0 mL of this solution was added mL volumetric flask and diluted to the...

question one question two Aspirin lab (10 points) 5. a) Spectroscopy is being used to determine the concentration of aspirin in an unknown sample. The absorbance spectrum of the highest concentration standard [Fe3+, SA) prepared is given below. What wavelength should be used to create the calibration curve for the experiment? Explain your reasoning. 0.14 Absorbance 0.02 250 300 450 500 350 400 Wavelength (nm) Wavelength Explain your reason briefly. b) In this experiment an aspirin tablet was placed in...
