E° Explorer
Pick two conventional reduction half-equations. The explorer shows which one runs as reduction, which one reverses for oxidation and how the overall cell reaction follows.
Choose two different redox couples to start.
Keep the notation conventional
The explorer always labels an E° value using the reduction couple in the same order as the tabulated half-equation. If the chemical reaction runs backwards, the reaction equation reverses; the name of the E° couple does not.
