Q: The reason for selection of wavelengths in the Spectrophotometry of Quinoline yellow

StrugglingChemistryStudentThe absorption spectrum for quinoline yellow has peaks at 224nm and 414nm, and a trough at 337nm. This experiment (See page 31), selects 224, 337 and 414nm to be used in the spectrophotometric analysis. As far as I have read, the wavelengths of maximum absorption (224nm, 414nm), give the best acc...
