Red dye can be made from a mixture of yellow dye and magenta (a deep purplish red) dye. How could you determine if a particular red dye is made from a single dye or from a mixture of yellow and magenta dyes?

When preforming the experiment the red dye will separate if it had other dyes included in it

Explanation:

Paper chromatography is a good way of separating coloured substances mixed together in a solution. During chromatography, the solvent soaks up the paper past the spot of the mixture and the different substances move upwards too. They move different distances depending on what kind of substance they are, what the solvent is and how far the solvent itself travels.
