Pigments can be separated by chromatography. Pigments which appear to be of a uniform colour can in reality be composed of several different-coloured substances. A further segregation of the prepared leaf pigment and a felt-tipped pen ink are shown in this experiment.
- Experiment guides are very easy to understand, especially for younger students
- Associated competences are directly linked to the experiments
- Curriculum compatible
- Fit for the future: implementation of tablets possible
