4 x 1 hour lessons

This module explores the variable oxidation states of transition metals and how they underpin redox chemistry. You’ll study redox titrations in detail, including how to construct half-equations and calculate unknown concentrations from titration data. The second half of the module focuses on the catalytic properties of transition metals and how these are linked to changes in oxidation state.

​

By the end of this module you will be able to:

• assign oxidation numbers to atoms in complex ions and compounds

• write and balance full and half redox equations

• solve problems involving redox titration data, including standardisation and unknown concentrations

• explain how transition metals act as homogeneous and heterogeneous catalysts

• describe how variable oxidation states contribute to catalytic behaviour

• evaluate the importance of redox catalysis in industrial and environmental processes
