40. If some of the water-soluble contents found in all of the meats tested in Experiment 2 absorbed light of the same wavelength as the compound formed with NO2- and the coloring agent, how would the measurements have been affected? Compared to the actual NO2- concentrations, the NO2- concentrations apparently measured would be:
Your Answer is
Correct Answer is F
Explanation
If all the meat used in Experiment 2 contained a soluble substance that also absorbs the same wavelength of light, then the measured absorbance should be higher.
Because the absorption is directly proportional to the concentration, the measured concentration will be higher than the actual one
