Thus is the limiting reagent as it limits the formation of product and is the excess reagent. A redox reaction consists of 2 parts, oxidation and reduction These two parts can be written up as half-equations where one half-equation shows oxidation and the other shows reduction. Therefore the excess reactant is carbon (ii) oxide. In this, oxidation state of an element increases. Chemical reactions that involve the transfer of electrons are called oxidation-reduction (or redox) reactions. Oxidation is the loss of electrons —or the increase in oxidation state—by a molecule, atom, or ion. Your email address will not be published.
