Hazard InformationBack Directory
[General Description]

Odorless white solid. Sinks in and mixes slowly with water.
[Reactivity Profile]

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.
[Air & Water Reactions]

Water soluble.
[Hazard]

Toxic by inhalation and ingestion.
[Health Hazard]

Inhalation of dust can cause systemic poisoning. Ingestion causes burning pain in throat, esophagus, and stomach; exposed areas of mucous membrane turn white; vomiting, severe purging, weak pulse, and cardiovascular collapse may result; if death is delayed, neuromuscular symptoms develop. Contact with eyes or skin causes irritation.
[Fire Hazard]

Behavior in Fire: Loses water at about 160° and decomposes to carbonate with no charring. The reaction is not hazardous.
[Chemical Properties]

Colorless, transparent crystals; odorless. Soluble in water.
[Chemical Properties]

The anhydrous salt, mol wt 166.22, is obtained when the monohydrate is dehydrated at 160 °C. The monohydrate is preferred as a reagent in analytical chemistry and in miscellaneous uses principally because of its high solubility as compared with other simple neutral oxalates.
