General Description

Odorless white solid. Sinks in and mixes slowly with water. (USCG, 1999)

Hazards

Reactivity Alerts

none

Air & Water Reactions

Water soluble.

Fire Hazard

Behavior in Fire: Loses water at about 160° and decomposes to carbonate with no charring. The reaction is not hazardous. (USCG, 1999)

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. (USCG, 1999)

Reactivity Profile

POTASSIUM OXALATE MONOHYDRATE 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.

Belongs to the Following Reactive Group(s)

First Aid

Act promptly!

INHALATION: remove victim to fresh air; if exposure to dust is severe, get medical attention.

INGESTION: call physician immediately; have victim drink dilute calcium lactate, lime water, chalk soln., or even milk; large amounts of calcium are required; administer gastric lavage with dilute lime water; watch for edema of the glottis and delayed constriction of esophagus.

EYES: flush with water and seek medical attention.

SKIN: flush with water. (USCG, 1999)
