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
The ultimate A level chemistry resource
Being confident in tackling different types of mole calculation is the foundation upon which much of A level chemistry stands
This is not just more exam questions with exam board style mark schemes. You can find plenty of those
The model of the atom we used at GCSE is not sufficient for A level but it is really important
In the reaction between peroxodisulphate ions and iodide ions, the iodide ions are oxidised to iodine whilst the peroxodisulphate ions
Virtually all transition metal compounds are coloured, a consequence of the way the 3d orbitals in the transition metal ion
Continue readingWhy are transition metal compounds coloured?
Coffee! Just kidding … In last month’s newsletter we saw that our brains learn by making mistakes. The harder you struggle to retrieve
Much of the chemistry of transition metal ions is a consequence of the fact that the 3d and 4s orbitals

Figuring out which cations and anions we might have in an unknown aqueous solution is a form of qualitative analysis.
Continue readingIdentifying anions and cations using chemical tests
a deep dive into the strategies that actually work There has been a surprising amount of research into how we
Identifying which ions we might have in a solution is known as qualitative analysis. The chemical tests we carry out

The ligands in a transition metal complex can be exchanged e.g. ammonia ligands replacing water ligands. This happens either because

In aqueous solutions of transition metal ion salts, the metal ion is invariably part of a complex known as an
