What are the reactants for oxidation reaction?
Alexxx [7]

The reactant that brings about the oxidation is called the oxidising agent, and that reagent is itself reduced by the reducing agent.

Oxidation occurs when a reactant loses electrons during the reaction. Reduction occurs when a reactant gains electrons during the reaction. This often occurs when metals are reacted with acid.

Oxidation is loss of electrons (OIL RIG). Therefore, an oxidising agent takes electrons from that other substance. Therefore, an oxidising agent must gain electrons.

Oxidation happens when an atom loses one or more electrons during a chemical reaction, meaning that its oxidation number increases. This is because the atom loses the negative charge of the electron, which is similar to gaining a positive charge, increasing the oxidation number.
