The chemical effect of the current consists in the release of substances from solutions during the passage of electric current through them – the phenomenon of electrolysis is used to produce pure metals. This can be demonstrated experimentally by passing a current through a solution of copper sulfate, obtaining pure copper on a negatively charged electrode.
