How to construct ionic equations for redox reactions by working out electron half equations and then combining them. Balancing of redox reactions Each reduction occurs at the same time as an oxidation, which consists in the loss of electrons by another chemical species, in such a way that the electrons are exchanged by the two chemical species. It describes the degree of oxidation (loss of electrons) of an atom in a chemical compound. This type of reaction can vary from a simple redox process (such as carbon oxidation, that generates carbon dioxide or carbon reduction from hydrogen, which produces methane) to the more complex oxidation of sugars in the human body, through a series of complicated electron transfer processes. Chemistry A-level OCR A revision notes. To change from one state to another requires the loss or gain of electrons.

A-Level Chemistry. -Redox reactions involve reduction and oxidation. We can balance the charges by including the electrons (which have negative charge) being transferred, and then we will get our reduction half-reaction right and balanced: now, if we add up the charges, including the electrons that have been transferred,  we end up with an overall charge of 0 at both sides of the reductions half-reaction. More links will be added over the next year and the A level chemistry notes expanded to cover more topics in the OCR A level chemistry course. 1.
