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...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
