Which of the following can result in deviations from Beer's law when the path length is constant? Solute concentrations exceeding 0.01 M The use of monochromatic radiation Stray light reaching the detector All radiation not absorbed by the sample is transmitted to the detector The absorbing species undergoes dissociation or association Incorrect. Beers law is only applicable when monochromatic radiation is used. Deviations can result when polychromatic radiation is used instead. The linear relationship between the absorbance and concentration described by Beer's law is only applicable when monochromatic radiation is passed through a dilute solution in which the absorbing species does not participate in a concentration-dependent chemical equilibrium. Deviations can occur when these conditions are not met or if light that has not passed through the sample reaches the detector.
