These downloadable resources investigate oxidation states.

The linked resources are adjuncts to the paper 'Redox reduxed: Application of a non-analogous definition for oxidation state' published in the September 2020 issue of ASTA's peer-reviewed Teaching Science journal (i.e., Issue 66.3). The paper, the abstract of which appears in the additional information field, investigates redox reactions and electrochemistry and the downloadable file named 'Appendix B - Redox and Electrochemistry Investigation' gives the details for a student investigation into the subject.

Teacher notes, a glossary of terms and example answers for the investigation are also provided.
