This experiment to be performed by students themselves, demonstrates how a mixture of salt and sand can be separated into its components. This involves adding some water to a mixture of solid salt and solid sand to make a suspension which is then poured through a filter paper. The sand ...
In the experiment introduced here, a mixture of water and methylated spirits made up by students themselves is to be separated into its components. The alcohol contained in the mixture will be distilled and collected in a conical flask. The simple distillation apparatus used here ...
Carbon dioxide can be obtained very simply from carbonates (e.g. marble) by dripping acid onto them. The properties of the gas obtained in this way can then be investigated with little difficulty. The student experiment described here demonstrates, among other things, two of the ...
With the help of the simple experiment set-up shown here, methane can be made from aluminium carbide and water. If the methane gas is collected in a test tube, it is then possible to investigate its properties.
Gases are condensing when they are cooled and at high
pressure. In this experiment butane is condensed by cooling it
to ca. -15 °C. In the second part of the
experiment butane is condensed by compressing it.
