3. follow a given set of chromatography method steps to separate the black ink solution into different solutes using the solvent water

4. label the origin line and solvent front line and in pencil, circle the different 'spots' that have separated out of the non-permanent black ink

5. make length measurements to calculate Rf values to show that each of the different spots are different solutes

6. carry out research to find out at least two key facts about the Russian scientist Mikhail Tsvet, who discovered the chromatography technique.
