Colourimetry and UV VIS Spectroscopy

IQ1: How are ions present in the environment identified and measured?

Students:

● conduct investigations and/or process data to determine the concentration of coloured species and/or metal ions in aqueous solution, including but not limited to, the use of:

– colourimetry

– ultraviolet-visible spectrophotometry

– atomic absorption spectroscopy

12. UV Vis Spectro and Precip Calcs

Presentation

This presentation reviews colourimetry and introduces UV Vis Spectroscopy.

Recall - we last saw colourimetry in Module 5 to determine the Keq of FeSCN equilibria.

USYD has some fantastic explanations of UV-Vis Spectroscopy with annotated spectra as examples.
