Basics of Chemistry II
When we take a closer look at substances, we discover that they consist of either one single element or of mixtures of several elements. Chemists therefore divide the world of substances into pure and mixed chemical substances. A pure substance is of homogeneous composition. Substance mixtures, however, consist of two or more pure substances. The many mixtures are subdivided not only into homogeneous and heterogeneous mixtures but depending on the respective aggregate states of their components, are classified into various groups of mixtures.

Basics of Chemistry I
We are surrounded by objects and substances. We recognise objects that are to serve a specific purpose by their shapes. Similar objects may consist of different materials or substances. Substances, however, are independent of shapes and possess very specific properties. We are able to perceive many of these substances with our senses. For example, we can see, touch or smell them so as to be able to recognise them. Chemists are particularly interested in those substance characteristics that can be measured. On the basis of these measurable properties they can distinguish between substances, identify a specific substance or test it for special use. Models help us to understand phenomena. They depict only specific elements of our reality, thus presenting the world in a simplified way. The spherical particle model, for example, helps us to understand how a scent spreads all over the room or substances disperse in water.

Aluminium II
The metal aluminium is growing in importance because of its specific properties and manifold application possibilities. This DVD deals with the industrial production of aluminium as a raw material, its processing and the manufacturing of alloys for the finished product. Starting with the raw material aluminium oxide the functioning of an electrolytic cell is demonstrated and explained. Alumina, white and powdery, is melted with great expenditure of energy, and by means of electrolysis converted into aluminium with a degree of purity of 99.9%. As aluminium oxide would not melt before a temperature of over 2,000°C is reached, the mineral cryolite is used as a solvent. The various alloys change the properties of aluminium and are produced according to precise formulations. The alloy is cast into blocks and bars that serve as primary material for processing plants. The responsible handling of resources underscores the importance of recycling. Aluminium is resilient and versatile.

Aluminium I
In the modern world, we encounter aluminium at every turn. This is due to the particular properties of the metal. Increasingly, aluminium is about to edge iron and steel out of engineering, as aluminium allows energy-saving lightweight construction of aircraft and vehicles of all kind. Aluminium is weather-resistant, does not rust and is therefore well suited as building material for house facades, window frames or simply for all parts that are exposed to wind and weather. At the same time, aluminium has a noble-looking surface recommending it as material for interior design.
