An inert electrode is a substance that is:

A) Sacrificed
B) Degraded
C) Present in the salt bridge
D) none of the above

An inert electrode is a substance, mainly a metal that only serves as the

source of the electrons and doesn't partake in the chemical reaction or

processes.

Inert electrodes are metals which are involved in the transfer of electrons

and chemical reactions involves exchange of ions which it's not involved in

the process.

The statement above about inert electrodes means that the most

appropriate answer is none of the above which is option D.

D) none of the above

Explanation:

An inert electrode is one that only serves as a source of electrons without playing a chemical role.It is normally present to allow current to flow through the cell.Gold and platinum are in most cases used as inert electrodes because they are chemically un-reactive.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

they are all solids.
