Topic 1 - Metal compounds: an
introduction to inorganic chemistry

Chemical Reactions

1. Recognise chemical reactions as precipitation, displacement, thermal decomposition and redox.
2. Demonstrate understanding of oxidation and reduction in terms of reaction with oxygen, change in ionic charge and change in oxidation number.
3. Recall the meaning of the terms: solution, solvent, solute and saturated solution.
4. Demonstrate the understanding of the terms solution, solvent, solute and saturated solution in the preparation of salts.
5. Describe the preparation of some iron compounds including double salts.
6. Describe salt (soluble and insoluble) preparations to produce dry crystals.

Atoms, Molecules and Stoichiometry

1. State the definition of relative atomic mass.
2. Define the terms relative atomic, isotopic, molecular and formulae masses based on the ¹²C scale.
3. Define the mole in terms of the Avogadro constant.
4. Calculate the relative atomic mass of an element given the relative abundance of its isotopes.
5. Determine atomic mass and/or isotopic abundance from an appropriate mass spectrum.
6. Define empirical and molecular formulae.
7. Calculate empirical and molecular formulae, using composition by mass.
8. Construct balanced chemical equations (full and ionic) for simple reactions, including state symbols.
