Thiocyanate complex formation. 0.1 M solution of iron (III) chloride is added to a beaker with 0.05 M solution of potassium thiocyanate (KSCN). Iron chloride solution has a yellow colour due to formation of hexaaquairon (III) complex ion ((Fe (H2O)6)3+). When potassium thiocyanate (KSCN) is added, iron (III) ion (Fe3+) complexes with thiocyanate ion ((SCN)-), producing thiocyanatoiron (III) complex ion ((Fe (SCN))2+) that gives the solution its blood red colour. This reaction can be used as a test for Fe3+ ions in a solution. | |
