Learning Outcomes

On successful completion of this module students should be able to:

* critically to assess chemical data for natural waters

* use chemical data to: calculate mass and charge balance for natural waters;

* calculate solubility

* use simple computer codes to predict speciation

* apply quality criteria to assess waters for human consumption

* describe the controls on water chemistry in terms of: solubility; acidity/alkalinity; hydrolysis; redox potential; buffering capacity; the role of colloid

* graphical representation of water chemistry data using a wide range of standard plots (e.g. Piper diagrams and Stiff diagrams)

Aims

A module to introduce the chemistry of natural waters. The module will consider the physical chemistry of the water molecule, variations in the chemistry of natural waters from the range of 'reservoirs' on the Earth. Topics covered will include the controls on element mobility such as solubility, hydrolysis, Eh/pH and the role of colloids. The module will introduce water quality standards for human consumption. A range of practicals will cover topics to include: the standard methods of displaying water chemistry data; calculation of mass and charge balance; solubility and solubility product. There will be two analytical practicals to introduce methods of analysis for determination of the inorganic chemistry of natural waters.
