BTEC APPLIED SCIENCE LAB REPORT ON OXIDATION AND REDUCTION. FND04: FURTHER CHEMISTRY FOR BIOSCIENCES - LAB REPORT Oxidation and Reduction (REDOX) Reactions Introduction Oxidation-reduction reactions, otherwise known as redox reactions, are fundamentally a process that involves a transfer of electrons. Oxidation can be defined as loss of electrons and reduction as gain of electrons. Therefore, oxidation results in an increase in oxidation number and reduction a decrease in oxidation numb...
