Question

How can you separate a combination of four lake pigment dyes (red, blue, orange, and inert binder) using these four solvents (NanoPure Water, Cyclohexane, Acidic Water, and Alkaline Water) based on these solubility test results.

Answer 1

If we dissolve the combination of four pigments in nanopure water then inert binders (IB) is insoluble in it and all other components dissolves in it. So, we can separate IB from others.

If we dissolve the combination of four pigments in cyclohexane then red dye is insoluble in it and other components dissolves thus, we can separate red dye from other components.

It is not possible to separate blue dye and orange dye from the combination because both have same solubility test.
