The information in CAMEO Chemicals comes from a variety of
data sources.
Reactivity Alerts
none
Air & Water Reactions
Hygroscopic. Gives basic solution, below 50°C dissolves in water and reacts to form the much less soluble potassium tetraoxalate, which separates out.
Fire Hazard
No information available.
Health Hazard
Inhalation of dust causes irritation of nose and throat. Ingestion causes burning pain in throat, esophagus, and stomach; exposed areas of mucous membrane turn white; vomiting, severe purging, weak pulse, and cardiovascular collapse; if death is delayed, neuromuscular symptoms develop. Contact with dust irritates eyes and may cause mild irritation of skin. (USCG, 1999)
Reactivity Profile
Salts, basic, such as POTASSIUM HYDROGEN OXALATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines.
POTASSIUM HYDROGEN OXALATE is a weak reducing agent, and may release carbon dioxide upon reaction with oxidizing agents.

First Aid
INHALATION: move to fresh air; if exposure to dust is severe, get medical attention.
INGESTION: give immediately by mouth a dilute solution of any soluble calcium salt (calcium lactate, lime water, chalk solution, or even milk); large amounts of Ca are required; administer gastric lavage with dilute lime water; consult physician; watch for edema of the glottis and delayed constriction of esophagus.
EYES: flush with water for at least 15 min.
SKIN: wash well with soap and water. (USCG, 1999)

data sources.
Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
