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.
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).
Plastic
Plastic has been around for not longer than roughly 100 years, and the synthetic material is a brilliant invention. Its production is cheap, it can take almost any possible form, it is light-weight, versatile and, above all, inexpensive.
