Mary Jane Simpson authored a quantitative teaching experiment on coloured drink solutions. A water blank, an absorption-peak scan, and serial dilutions connect absorbance with concentration.
The experiment separates visual colour comparison from an instrumental measurement. Quantitative transfer and final-volume calibration matter because dilution ratios are part of the inferred chemical amount.[ref]
