Adding an inert electrode

Postby ShravanPatel2B » Sat Feb 29, 2020 7:43 pm

When do we know to add an inert electrode such as Pt to our cell diagrams when doing exercises such as 6l.5 part D. Thanks!

You add Pt if there are no solids involved in the reduction or oxidation reactions.

You add Pt when there is no solids involved in the galvanic cell for either the reduction or oxidation reactions.

Adding on to the answers above, you use an inert electrode if there is no solid METAL. An example is Iodine, I2(s). You would still have to use an electrode for half-reactions involving solid iodine since it is technically a gas/nonmetal.
