Ferric Alum Indicator

Ferric Alum Indicator is Chemical indicators used as oxidation reduction indicators.

Remarks

Dust mask; goggles or face shield; protective gloves (USCG, 1999)

First Aid : INGESTION: give large amount of water; induce vomiting if large amounts have been swallowed.  

EYES or SKIN: flush with water. (USCG, 1999)

Tag Identification

Ferrous Ammonium Sulfate solutions are used as reductometric standards in titrations involving Ceric, Dichromate and Permanganate ions, as well as other oxidizers. Since Ferrous ion is easily oxidized by air to Ferric ion, Ferrous Ammonium Sulfate solutions are not as stable as other reductometric standards such as Arsenic Trioxide and Sodium Oxalate solutions, but they do not have the toxicity or environmental problems of the others. Because of this inherent instability, it is recommended that Ferrous Ammonium Sulfate solutions be restandardized periodically when extreme accuracy is required

Note

Soluble in water that forms weakly acidic solutions. Deliquesces in air.
