Halogens
The compounds of halogens are - with the exception of astatine - widespread, can be encountered in nature and are versatile substances. This fact is taken up on this DVD in order to teach the students the chemistry of the halogens by illustrating their special qualities and explaining the correlation of their structure with their chemical properties. In the first part, an overview of the element group of halogens lays emphasis on the common as well as on the distinguishing characteristics of fluorine, chlorine, bromine and iodine. In a second part, the specific properties of fluorine and chlorine are presented. This topic is linked to the students‘ everyday experience (fluorine as a protection against caries, chlorine as a disinfectant, etc.) on the one hand. On the other hand, the DVD presents carefully selected experiments. As a rule, they are of a kind that can only be realized with difficulty, or high expenditure in the chemistry classroom. With the help of these experiments, students are introduced to the chemistry of the halogens in a way that enables them to draw conclusions on the basis of their observations.
Acids and Bases
We can find acids and bases in every supermarket, some of them in our food, others in cleaning agents. In everyday products, acids and bases as well as acidic and alkaline reacting salts have extremely different functions. In food, acids are either present or added as flavouring agents such as citric acid, tartaric acid and acetic acid, as antioxidants such as ascorbic acid or generally as acidifiers, sequestrants (citric acid and tartaric acid) and preservatives (acetic acid).
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.
