4 x 1 hour lessons

This module introduces the properties and chemistry of transition metals. You’ll study variable oxidation states, complex ion formation, colour, and redox behaviour. You’ll also explore their use as catalysts and practise writing ligand substitution and redox equations involving transition metal ions.

​

By the end of this module you will be able to: • define transition elements and explain characteristic properties • describe common oxidation states and their stability • explain the formation of coloured compounds • describe and write equations for ligand substitution reactions • • interpret colour changes and observations in test-tube reactions • predict formulae and shapes of complex ions
