a) For your cereal sample, you added the same volume of sodium acetate that you added to your standards and solution unknown. b) You forgot to add hydroxylamine hydrochloride when you prepared the standards, but you added it when you did the cereal analysis. For part b, include a sketch of a Beer's Law plot to explain how the error would affect the calibration line and the with the determined for the cereal. (Onthe sketch, use a solid line to represent the correct calibration line and a dotted line for the line with the systematic error.) Also discuss the advantages and disadvantages of spectral methods of analysis.
