Chemistry

Unit 3 - Section 11 - Redox Reactions

Learning Outcomes


- An Oxidising Agent is a substance that causes another chemical to be oxidised, it itself is reduced. (it is an electron acceptor)

- A Reducing Agent is a substance that causes another chemical to be reduced, it itself is oxidised. (it is an electron donor)

- The strongest oxidising agents start at the bottom left hand side of the Electrochemical Series and the weakest start at the top left hand side.

- The strongest reducing agents start at the top right hand side of the Electrochemical Series and the weakest start at the bottom right hand side.

- 96,500 coulombs is the charge associated with 1 mole of electrons.

- The production of 1 mole of an element from its ion by electrolysis, always requires n times 96,500 coulombs, where n is the number of electrons in the relevant half equation.
