Complex ions and oxidation states

Complex ions and oxidation states

Many aqueous transition metal ions are actually complex ions such as [Cu(H2O)6]2+[\text{Cu}(\text{H}_{2}\text{O})_{6}]^{2+}[Cu(H2​O)6​]2+. A ligand donates a lone pair to the metal ion, so most reactions either change the ligands or change the oxidation state of the metal.

  3. /Transition metal reactions and catalysis

Step-by-step lessons covering Edexcel A Level Chemistry Transition metal reactions and catalysis for A Level Chemistry. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
