Calculations for AS and A level Chemistry
Being confident in tackling different types of mole calculation is the foundation upon which much of A level chemistry stands

When is an answer NOT actually an answer?
when your answer is in fact just your working out … This is without doubt the most frustrating thing examiners
Coordination chemistry
The coordination number of a complex is the number of atoms making coordinate or dative covalent bonds to the central
What is a complex ion?
d-block metal cations readily form complexes with ligands – neutral molecules such as water or anions such as the chloride
