A redox reaction, also known as oxidation-reduction reaction, is a type of chemical reaction that involves the transfer of electrons between two chemical species. There are several synonyms for the term redox reaction, including electron transfer reaction, oxidation-reduction process, oxidation-reduction reaction, oxidation reaction, reduction reaction, and redox process. These terms are often used interchangeably in chemical literature to describe the same type of reaction. The importance of redox reactions in various chemical processes cannot be overstated, as they play a vital role in cellular respiration, photosynthesis, and many other chemical reactions occurring in our environment and day-to-day life.
