GCSE Chemistry - Paper Chromatography #63

The video tutorial explains chromatography, focusing on paper chromatography used to separate dyes in ink. It details the process, including setting up the experiment with filter paper and solvent, and observing how different dyes travel at different rates. The concepts of mobile and stationary phases are introduced, explaining how they affect the movement of substances. The tutorial also covers calculating RF values to identify chemicals, noting that results vary with different solvents or paper types.

What is an RF value and how is it calculated?

What happens to a pure substance during chromatography?

Why is it important to consider the solvent and paper type when interpreting RF values?
