What are reactive electrodes and inert electrodes? Give examples.
(N/A) $1$. Reactive Electrode: These electrodes participate in the electrochemical reaction during electrolysis or in a galvanic cell. They either get oxidized or reduced during the process. Example: $Cu$ electrode in a copper sulfate solution.
$2$. Inert Electrode: These electrodes do not participate in the chemical reaction (neither oxidized nor reduced) but only provide a surface for the transfer of electrons. Example: $Pt$ (Platinum) or Graphite electrodes.
