Edexcel IAL Chemistry A2 17.6 complex ion definition
The evidence is narrow: identify a species as a complex ion and write the relevant aqueous iron complex formula when ligand surroundings are given.
How this is tested
- Recognise complex ions as transition-metal species containing ligands around a metal ion.
- Write formulae such as [Fe(H2O)6]3+ for aqueous transition-metal complexes.
