In an aqueous solution, copper ions can form the complex ion [Cu(H 2 O) 6 ] +2 (aq). In [Cu(H 2 O) 6 ] +2 (aq),

[Cu(H 2 O) 6 ] +2 (aq) is a complex ion because it contains a metal ion (Cu +2 ) surrounded by ligands (H 2 O). H 2 O is a ligand because it donates a pair of electrons to the metal ion. Cu +2 is an acceptor because it accepts a pair of electrons from the ligand.
