Pt as an electrode

Postby Samantha Chung 4I » Thu Feb 21, 2019 12:42 am

Why is platinum often selected as an electrode?

Inert electrodes, like the platinum electrode do not participate in the oxidation-reduction reaction and are present so that current can flow through the cell. Platinum or gold generally make good inert electrodes because they are chemically nonreactive.

the mass of an inert electrode does not change during the oxidation-reduction reaction; inert electrodes are often made of platinum or gold because these metals are chemically unreactive.

Platinum is an inert electrode which means it will not interfere or react with the chemical redox reaction and skew results

Being an inert and unreactive electrode means that it will not give or take any electrons during the reaction. This leaves the reduction and oxidation reactions to the reactants in question.
