Reduction is equivalent to a gain of electrons.
when a substance can not be chemically reduced
Which element will be oxidized and which will be reduced
The element forming at the cathode will depend on what elements are present. Reduction takes place at the cathode, so whatever element is being reduced, that is the one that will be produced at the cathode.
When a reactant is reduced, it gains electrons. Thus, metal cations can be reduced to neutral metal atoms.
