Ferric phosphate

Description

Ferric phosphate (ferric orthophosphate, iron (III) phosphate, FeP04xH2O) is an odorless, yellowish-white to buff-colored powder and contains from one to four molecules of water of hydration. It is prepared by reaction of sodium phosphate with ferric chloride or ferric citrate. It is insoluble in water and in acetic acid, but is soluble in mineral acids.

Chemical properties

Yellowish-white powder. D 2.87. Insoluble in water; soluble in acids.

Chemical properties

This is precipitated as yellowish-white FePO4.2H2O when a solution of disodium phosphate is added to a solution of an iron(III) salt. It is soluble in mineral acids and decomposed by hot aqueous ammonia. The decolorization of iron (III)chloride solutions by phosphoric acid is due to the formation of colourless phosphato complexes, e.g. [Fe(PO4)3]6-.

The Uses of Ferric phosphate

Ferric Phosphate is a nutrient supplement that is an odorless, yellow- ish white to buff-colored powder and contains one to four molecules of water of water of hydration. it is prepared by reaction of sodium phosphate with ferric chloride or ferric citrate. it is also termed iron (ii) phosphate.

The Uses of Ferric phosphate

Fertilizers, feed and food additive.

The Uses of Ferric phosphate

Ferric phosphate is an inert white powder that is a source of iron and produces no discoloration or rancidity. It contains approximately 28% iron. It is used as a mineral supplement where rancidity is not a problem. It is used in frozen egg substitute, pasta products, and rice products.
