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 bromine and iodine are presented. This topic is linked to the students‘ everyday experience on the one hand (bromine as a catalyst for reactolite sunglasses, iodine as an agent in medicine, etc.) on the one hand. 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.
Solutions, Emulsions and Mixtures of Substances
Be it milk in a cereal bowl, tea in a glass or the air around us. We constantly come across mixtures of substances in our everyday lives. As the name suggests, they are mixtures – mixtures of several so-called pure substances.
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.
