38% Solution Iron III Chloride Ferric Chloride
Ferric Chloride Solution
Iron(III) chloride, also called ferric chloride, is an industrial scale commodity chemical compound, with the formula FeCl3 and with iron in the +3 oxidation state. The colour of iron(III) chloride crystals depends on the viewing angle: by reflected light the crystals appear dark green, but by transmitted light they appear purple-red. Anhydrous iron(III) chloride is deliquescent, forming hydrated hydrogen chloride mists in moist air. It is rarely observed in its natural form, mineral molysite, known mainly from some fumaroles.
Application of Ferric Chloride Solution
a.Used in water and wastewater treatment to precipitate phosphate as iron(III) phosphate.
b.Used to make printed circuit boards (PCBs).
c.Necessary for the etching of photogravure plates for printing photographic and fine art images in intaglio and for etching rotogravure cylinders used in the printing industry.
