Chemistry - Redox Reactions Question with Solution | TestHub

Oxidation and reduction reactions ocurring simultaneously are called redox reactions. Oxidation involves loss of electrons while reduction involves gain of electrons. As a result, oxidation number of an atom increases during oxidation and decreases during reduction. The redox reaction may involve combination of atoms or molecules, displacement of metals or non-metals and disproportionation reactions. Redox reactions may be balanced by oxidation number method or ion-electron method.
