19.1.3 Calculate cell potentials using standard electrode potentials

19.1.4 Predict whether a reaction will be spontaneous using standard electrode potential values

Topic 19: Oxidation and reduction

Topic 19 of the IB HL Chemistry syllabus is the Oxidation and reduction. IBO recommends to spend 5 hours on this topic.

This topic has 2 sub-chapters: "Standard electrode potential", and "Electrolysis". Each are separated with numerical values in order of mentioned.

These are advanced HL syllabus statements, it is recommended to bring a Casio Graphical Calculator instead of Texas. Casio Calculators have the periodic table installed already.
