These are ion-exchange reactions and redox reactions. Oxidation-Reduction (RedOx) Reaction • An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a Combination Reactions. Conditions. The redox titration is also known as an oxidation-reduction reaction. These are known as disproportionation reactions. Oxidation is termed as the Removal of an electron whereas Reduction is termed as the Addition of an Electron. Ion exchange reactions include precipitation reactions, gas forming reactions and acid-base reactions. In these reactions one of the reacting substances always contains an element that can exist in at least three oxidation states. Types of reactions A combination reactions may be denoted in the manner: A + B – C. For the above reaction to be a redox reaction.
