Metal aquo complex

In <a href="/facts/Chemistry/SrNqkGVm">chemistry</a>, metal aquo complexes are <a href="/facts/Coordination_compound/1tCyeQUm">coordination compounds</a> containing metal ions with only <a href="/facts/Water/0lkXnJPK">water</a> as a <a href="/facts/Ligand/6etB3qeW">ligand</a>. These complexes are the predominant <a href="/facts/Chemical_species/A8BxM3oW">species</a> in <a href="/facts/Aqueous_solution/eRNr3MH2">aqueous solutions</a> of many metal <a href="/facts/Salt_(chemistry)/lsSKwGpn">salts</a>, such as metal <a href="/facts/Nitrate/5AnVlYnL">nitrates</a>, <a href="/facts/Sulfate/yuWVxsUf">sulfates</a>, and <a href="/facts/Perchlorate/WCC53zS2">perchlorates</a>. They have the general <a href="/facts/Stoichiometry/I5p9cJzV">stoichiometry</a> [M(H2O)n]z+. Their behavior underpins many aspects of <a href="/facts/Environmental_chemistry/ByvgBKNs">environmental</a>, <a href="/facts/Biochemistry/fa2pWEBp">biological</a>, and <a href="/facts/Industrial_chemistry/3M6gfHer">industrial chemistry</a>. This article focuses on complexes where water is the only ligand ("<a href="/facts/Homoleptic/QjKkfHqS">homoleptic</a> aquo complexes"), but of course many complexes are known to consist of a mix of aquo and other ligands.
