WebOxidation and reduction in terms of oxygen transfer. Definitions. Oxidation is gain of oxygen. Reduction is loss of oxygen. For example, in the extraction of iron from its ore: Because both red uction and oxi dation are going on side-by-side, this is known as a redox reaction. WebOxidation and Reduction Chemistry Questions with Solutions. Q1. The reaction in which oxidation and reduction co-occur is known as (a) Redox reaction (b) Oxiduction reaction (c ) Both a and b (d) None of the above. Answer: (a) The reaction in which oxidation and reduction co-occur is known as a redox reaction. Q2. Oxidation refers to the (a ...

Weboxidation-reduction reaction, also called redox reaction, any chemical reaction in which the oxidation number of a participating chemical species changes. The term covers a large and diverse body of processes. WebRedox chemistry describes reactions in which one component is oxidised (loses electrons) and another component is reduced (gains electrons). There are two well-known, classroom-based redox titrations: 1. Determining the concentration of Fe 2+ ions in solution The underlying chemistry of the redox reaction is shown below.
