Aim
The course shall give relevant knowledge about chemical processes in fresh water and models for understanding the interplay between humans and environment as well as ability to carry out numerical water chemistry calculations.. The course shall also give ability to evaluate environmental problems in accordance with a scientific view in all society.

Knowledge and understanding
For a passing grade the student must

Have good knowledge about pH and buffer systems and be able to see the connections to natural systems
• Be familiar with the fundamental concepts of aquatic chemistry: ANC, alkalinity, DOC, solubility and rexoxprocesses

• Be familiar with the thermodynamic relation to electrochemistry and its applications in water chemistry

• Interpret and plan for problems and questions in accordance with the water chemical model

Skills and abilities
For a passing grade the student must

Be able to plan and perform calculations with aquatic chemistry using MATLAB
• Be able to write electrochemical cells and analyse the reactions for electrochemical processes with special applications in aquatic chemistry e.g. potential/Eh - diagrams

• Be able to report results from water chemistry laboratory work in a correct and clear manner.

Judgement and approach
For a passing grade the student must

• Be able to present and interpret calculations in a logical and relevant way

• Have the skill to present results of projects that have been carried out during the course and discuss these with teachers and fellow students

Contents
In connection with realistic applications, chemical and physical processes focused on the environmental systems water and air, will be explained for central chemical processes such as acid/base reactions, gas/water exchange reactions, buffering systems, titration strategies, solid phase/liquid reactions, redox processes and redox buffering. A methodology for computational water chemistry is developed during the course. Emphasis is put on the students’ ability to interpret water chemistry processes, systems and calculations. A core element is that the students should support eachothers learning by an active an reflecting approach in groups. The laboratory work is mandatory and offers an opportunity for the students to get a personal experience of the processes treated theoretically, and to get insight in how chemical analysis may be handled professionally.

Work with problem solving plays an important role throughout the whole course.
