= Ultraviolet-Visible Spectrophotometry =

Proposed Topics

 * Ultraviolet–visible spectroscopy
 * Absorption spectroscopy
 * Thymol blue

Outline
=== Ultraviolet-Visible Spectroscopy ===
 * 1) Show what a spectroscopy is.
 * 2) Describe the experiment this equipment is used for.
 * 3) Relate this to molecular absorption of ultraviolet and visible regions.

=== Absorption Spectroscopy ===
 * 1) Explain why at different pH, the rate of absorption is different.

Thymol blue

 * 1) Define what thymol blue is.
 * 2) Add in diagrams of thymol blue at different pH.
 * 3) 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.
