POTASSIUM OXALATE Chemical Properties

MF: C₂K₂O₄
MW: 166.22
EINECS: 209-506-8
Synonyms:DI-POTASSIUM OXALATE; dipotassiumethanedioate; Ethanedioicacid, dipotassiumsalt; oxalicacid,dipotassiumsalt;potassiumneutraloxalate;potassiumoxalate(k2c2o4);Potassium Oxalate Anhydrous;Potassium oxalate
POTASSIUM OXALATE's structure:

Potassium oxalate(583-52-8) gives basic aqueous solutions. Reacts as a base to neutralize acids in reactions that generate heat, but less than is generated by neutralization of the bases in reactivity group 10. Can serve as a reducing agent in reactions that generate carbon dioxide.

POTASSIUM OXALATE Uses

Reagent in analytical chemistry, source of oxalic acid, bleaching and cleaning, removing stains from textiles, photography.

POTASSIUM OXALATE Toxicity Data With Reference

Organism	Test Type	Route	Reported Dose (Normalized Dose)	Effect	Source
women	LDLo	oral	1gm/kg (1000mg/kg)	CARDIAC: ARRHYTHMIAS (INCLUDING CHANGES IN CONDUCTION) VASCULAR: SHOCK GASTROINTESTINAL: OTHER CHANGES	Medecine Legale et Dommage Corporel. Vol. 4, Pg. 178, 1971.

POTASSIUM OXALATE Consensus Reports

Potassium oxalate(583-52-8) is reported in EPA TSCA Inventory.

POTASSIUM OXALATE Safety Profile

Human systemic effects by ingestion: cardiac arrhythmias, shock, gastrointestinal changes. When heated to decomposition it emits acrid smoke and irritating vapors.

POTASSIUM OXALATE Standards and Recommendations

DOT Classification: 6.1; Label: KEEP AWAY FROM FOOD

POTASSIUM OXALATE Specification

1、Handling and Storage of Potassium oxalateStorage(583-52-8)
