Solutions, Emulsions and Mixtures of Substances
Properties and Uses
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. They are, for instance, the chemical elements listed in the periodic table. These are substances that only consist of one single element, for example sulphur. But there are also pure chemical compounds such as distilled water or sodium. If you solve sodium or other substances in regular water, the result is a mixture of substances. A mixture is formed from different chemical compounds. With mixtures of substances like this, the source substances remain in the mixture as individual units – even if you cannot distinguish them with the naked eye. Nevertheless, they can be divided into their individual components with the help of various separation methods.
