ferÂ·ric chloÂ·ride test. a qualitative test for the detection of phenylketonuria; the addition of ferric chloride to urine gives rise to a blue-green color in the presence of phenylketonuria.

Ferric Chloride is FeCl3 and Ferrous Chloride is FeCl2. Ferric Chloride contains Iron+3 and Ferrous Chloride contains Iron+2. Ferric Chloride may react with pure Iron and create ferrous chloride.
