Exhibition Chemistry: Migration of coloured ions by electrolysis

Description

There are many examples in the literature of ion migration, such as copper(II) sulfate or potassium manganate(vii), either in solution or solid phase. However, to find an example where both cation and anion movement can be observed in a single compound is relatively rare.
