Respuesta :

The mass of a metal acting as an anode will decrease because electrons always move from an anode to a cathode or from the oxidation half cell to the reduction half cell.

Reduction vs. Oxidation

  • In a type of chemical reaction known as a reduction-oxidation or redox reaction, reduction and oxidation take place concurrently.
  • While the reduced species gets electrons, the oxidized species loses electrons.
  • Despite the name, an oxidation reaction doesn't require the presence of oxygen.

What is an electrode for oxidation and reduction?

Usually applied to electrodes when an inert metal is dipped into a solution containing ions of the same element in two different oxidation states, this word is used to describe these electrodes. A type of chemical process called oxidation-reduction involves the transfer of electrons from one material to another.
