Iron test. Thiocyanate complex ([FeSCN]2+) in a test tube. The complex was formed by adding potassium thiocyanate (KSCN) to a solution of iron (III) ions and water. The addition of potassium thiocyanate turns the yellow iron (III) ion and water solution a distinctive deep red. A bottle of potassium thiocyanate is beside the test tube rack.
