OCR Chemistry redox reactions + titrations

A complete lesson covering section 5.2.3 a- e of the OCR Chemistry specification - redox reactions and carrying out redox titrations.

The lesson opens with a reminder of oxidation numbers from year 12. It then looks at reducing and oxidising agents using an example to reinforce the idea. The lesson then moves onto how half equations can be used to construct overall equations for reactions, again with students led practice. It then looks at using oxidation numbers to complete equations, including when some species are missing from the equation (such as water) .

The final part of the lesson looks at redox titrations including both how to carry them out as well as various examples of calculation including calculating purity and using it to work out water of crystalisation.

The lesson includes worked examples and student independent practice.
