platinum electrode

Postby Sarah Blake-2I » Fri Feb 28, 2020 10:17 pm

When do we add a platinum electrode to the outside of a cell diagram for a redox reaction and what is the reasoning behind adding a platinum electrode? Would it be acceptable to just insert an electrode of the same element in the solid form or must it always be platinum when there is no given electrode?

You would add a platinum when there is no solid electrode present in the reaction. The reasoning behind adding this platinum electrode is because it is a good inert conductor that does not get too involved in the redox reaction.

The absence of a solid in your reaction would require the use of platinum as an electrode. As mentioned above, the fact that it is a good conductor will prevent it from interfering with the reaction.
