Inert metallic component

[305920501]

Is there a way to know what inert metallic component is ideal for the electrode in each reaction? Should we always use platinum for hydrogen? Is platinum a metal we can use for other reactions as well, and how do we know which reactions need the electrode to be constructed of a different metal?

The choice of inert metallic component for an electrode depends on various factors, including the specific redox reaction being studied and the compatibility of the metal with the reactants and products. While platinum is commonly used for many reactions, such as the hydrogen evolution reaction, other metals like gold, silver, and graphite may also be suitable depending on the reaction conditions and requirements. However, they are likely not used unless necessary due to the costs of the metals (gold and silver).
