Using transition metal ions as catalysts
In the reaction between peroxodisulphate ions and iodide ions, the iodide ions are oxidised to iodine whilst the peroxodisulphate ions
Why are transition metal compounds coloured?
Virtually all transition metal compounds are coloured, a consequence of the way the 3d orbitals in the transition metal ion

Hacks to supercharge your learning
Coffee! Just kidding … In last month’s newsletter we saw that our brains learn by making mistakes. The harder you struggle to retrieve
Explaining the redox behaviour of transition metals
Much of the chemistry of transition metal ions is a consequence of the fact that the 3d and 4s orbitals

Identifying anions and cations using chemical tests
Figuring out which cations and anions we might have in an unknown aqueous solution is a form of qualitative analysis.

How to learn better!
a deep dive into the strategies that actually work There has been a surprising amount of research into how we
How to identify transition metal ions in solution
Identifying which ions we might have in a solution is known as qualitative analysis. The chemical tests we carry out

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

Understanding the acid-base behaviour of aqueous transition metal ions
In aqueous solutions of transition metal ion salts, the metal ion is invariably part of a complex known as an

Isomerism in transition metal complexes
Structural isomers These are compounds with the same number and type of atoms but the atoms are bonded in different
