Relate this to molecular absorption of ultraviolet and visible regions. Absorption Spectroscopy[2] [ edit ] Explain why at different pH, the rate of absorption is different. Thymol blue [ edit ] Define what thymol blue is.
Add in diagrams of thymol blue at different pH.
Relate this to UV-Vis Spectrophotometry. a dye used as an acid-base indicator, with a pK value at 1.7 and another at 8.9; red at pH values below 1.2, yellow between 2.8 and 8, and blue above 9.6.[3] References [ edit ]
