Description

To determine the potential of a half-cell, a reference parameter is necessary. By international agreement, the half-cell H₂/H₃O⁺ has been established as reference cell. That standard hydrogen electrode has been arbitrarily assigned the potential E⁰ = 0.00 V. In experiment C4.4.3.2, a standard hydrogen electrode is used to measure the standard potentials of various metals. This can be done either with the demonstration unit for electrochemistry or with CASSY and the prefabricated standard hydrogen electrode HydroFlex.
