IB Chemistry 3.2.1 Oxidation and reduction Questions
Track oxidation and reduction by electron transfer, oxidation-state change, and the exact role each species plays in the reaction.
How this is tested
- identify the species oxidized and electrons lost from an equation, e.g. SO3^2- -> SO4^2- + 2e-
- distinguish oxidizing and reducing agents in spontaneous redox, e.g. S2O8^2- oxidizes C2O4^2-
- recognize organic oxidation from structural change, e.g. H2CO to HCOOH is oxidation of the carbon
