Aquation
From Infogalactic: the planetary knowledge core
Aquation is the chemical reaction involving "incorporation of one or more integral molecules of water".[1] The term is typically employed to refer to reactions of metal complexes where an anion is displaced by water. For example, bromopentaamminecobalt(III) undergoes the following aquation reaction to give a metal aquo complex:[2]
- [Co(NH3)5Br]2+ + H2O → [Co(NH3)5(H2O)]3+ + Br-
This aquation reaction is catalyzed both by acid and by base. Acid catalysis involves protonation of the bromide, converting it to a better leaving group. Base hydrolysis proceeds by the Sn1CB mechanism, which begins with deprotonation of an ammonia ligand.
