Question

When connected to a hydrogen electrode, an electrode with a negative standard reduction potential will carry out



reduction


oxidation


both oxidation and reduction


neither oxidation or reduction

Answer 1

• both oxidation and reduction take place.

• Oxidation can be defined as the chemical reaction that takes place through the transfer of electrons from one chemical substance to another.

• these processes of electron-transfer reactions are termed oxidation-reduction reactions.

• Reduction is a process that  involves the addition of hydrogen or an electropositive element or the removal of oxygen or from any electronegative element.
