Aim
The course shows how chemistry can explain molecular phenomena in industry and in the environment. The course should create an interest in chemistry, and build a theoretical and practical basis for continued studies in chemistry within the Environmental Engineering program. The course builds the foundation for the following courses: Organic Chemistry, Thermodynamics and Surface Chemistry, Molecular Cellbiology, and Aquatic and Atmospheric Chemistry.

Contents
The theme of the course is Water. The theme will be used to exemplify applications in, for example, biological processes, lakes and oceans, and corrosion. In connection to aquatic processes, chemical principles will be described and explained.

The following topics will be covered:

Functional groups in organic molecules, their nomenclature and properties.
General introduction to enthalpy, entropy and free energy.
Enthalpy of formation and combustion. Calorimetry.
Chemical equilibria with applications such as solubility, acid-base reactions, buffersolutions and titration.
Electrochemistry including redox-processes and the properties of metals, exemplified by, e.g., corrosion and electrochemical cells.
Intermolecular forces (hydrogen bonds, van der Waals forces) are treated together with the concepts hydrophobic and hydrophilic.
Properties of solutions (vapour-pressure lowering, boiling-point elevation, freezing-point depression).
The structure of proteins and membranes. The energy metabolism of the cell.
Analytical methods focussed on water and environmental analysis. The analytical methods are presented in connection to relevant parts of the course and exemplified during laboratory experiments.

The laboratory experiments will cover selected topics of the course and are compulsory.
