Half cell

From Free net encyclopedia

A half cell is a structure that contains an electrode and a surrounding electrolyte. A standard half cell, used in electrochemisty, consists of a metal electrode in a 1 molar aqueous solution of the metal's salt, at 298 Kelvin. The electrochemical series, which consists of standard electrode potentials and is closely related to the reactivity series, was generated by measuring the between the metal half cell in a circuit with a standard hydrogen half cell, connected by a salt bridge.Template:Chem-stub
