Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.

Answer 2

Answer:

A reaction in which one reactant undergoes oxidation whereas the other gets reduced during the course of reaction are termed as oxidation-reduction reactions or redox reactions. ... Reduction refers to the gain of electrons or decrease in oxidation state by a molecule, atom, or ion. Consider the following redox reaction.

Oxidation-reduction reaction, also called redox reaction, any chemical reaction in which the oxidation number of a participating chemical species changes.

An oxidation-reduction reaction is any chemical reaction in which, by obtaining or losing an electron, the oxidation number of a molecule, atom, or ion varies. An example of a redox reaction is the formation of hydrogen fluoride. ... The photosynthesis reaction is sensitised by chlorophyll.

Redox reactions are chemical reactions involving oxidation and reduction occurring simultaneously. Therefore, redox reaction is also known as oxidation-reduction reaction.
