ncert.nic.inreactions. One important category of such reactions is Redox Reactions. A number of phenomena, both physical as well as biological, are concerned with redox reactions. These reactions find extensive use in pharmaceutical, biological, industrial, metallurgical and agricultural areas. The importance of these reactions is apparent from the fact
Chapter 10 Chemical Reactions
web.gccaz.edu10.9 Redox Reactions Many single replacement, combination, decomposition and combustion reactions are also redox reactions. Redox is short for reduction and oxidation. Reduction is when an element’s charge goes down and oxidation is when an element’s charge goes up. Note you can’t have reduction without oxidation and vice versa.
