WebComplex-Ion Equilibria Some cations form soluble complex ions, which are formed when a metal ion with a Lewis base attaches to it by a coordinate covalent bond. Their formation increases the solubility of a salt containing those cations. Metal ions that form complex ions include most transition elements. Ligands are Lewis bases that bond to a metal ion to … WebMar 26, 2009 · Description. Iron (III) chromate is a chemical compound of iron and hexavalent chromium.
