Iron(III) Chloride and Yellow

Also called ferric chloride, iron(III) chloride is a chemical used in many industrial and other processes, including to make a primary colour solution for the colour yellow. In solid state, iron chloride crystals vary in colour depending on the viewing angle. With reflected light, the crystals look dark green, but with transmitted light they look red-purple.

When added to water, iron chloride undergoes hydrolysis and releases heat in an exothermic reaction. In addition to being used as a primary colour solution, this compound is also used in many other applications:

  • Flocculant in sewage treatment
  • Enchant in copper-based metals in printed circuit boards
  • Catalyst in the reaction of ethylene with chlorine
  • Catalyst in the chlorination of aromatic compounds
  • Ferric chloride test
  • Used to precipitate phosphate in water treatment
  • Used in welding to etch the metal, to produce a contrasting effect
  • Etching of photogravure painting in photos and fine art prints
  • Etching cylinders used in the printing industry
  • Used to test over cropping of pet’s claws, especially if bleeding
  • Used in the synthesis of ferrocene
  • used in pottery to colour pieces shades of brown and orange
  • Used to test resistance to corrosion of stainless steel and other alloys
  • Used to synthesis primary amines
