What is the reason for analyzing a blank in the spectrophotometer before analyzing the standard solution? A. any absorbance of light by the solvent AND the cuvette needs to be accounted for B. any absorbance of light by the cuvetto needs to be accounted for C. so the scattered light is filtered before reaching the photodiode D. to account for any fingerprints on the cuvette E. any absorbance of light by the cuvette and fingerprints needs to be accounted for
