Description
Apearances: Reddish-brown liquid, its solution is acidic. Strong corrosive effect on metal. 282 ° C melting point, boiling point of 315 ° C, soluble in water and has strong water absorption, can absorb moisture from the air and deliquescence. FeCl3 with six crystal water from the aqueous solution precipitated FeCl3 ? 6H2O, ferric chloride hexahydrate orange crystals. Ferric chloride is a very important molysite.
USES
Mainly used for industrial water treatment, printing plate etchant, etching and surface treatment of stainless steel, industrial oxidant and mordant dyes, organic synthesis industrial catalysts and manufacturing other molysite raw materials.
