Half-wave potential (E1/2) is a potential at which polarographic wave current is equal to one half of diffusion current (id). In a given supporting electrolyte, the half-wave potential is unique for each element and its different valence states and chemical forms. Observation of a current peak at a specific half-wave potential therefore identifies the chemical species producing the current.
