그림문자(GHS)

화학적 성질
Colorless, transparent crystals; odorless. Soluble in water.
용도
Potassium oxalate is a white crystal or powder made by neutralizing oxalic acid with potassium carbonate. It is soluble in water 1:3 but not in alcohol. Potassium oxalate was used as an early developer for gelatin plates but is best known as the developer for platinum prints.
일반 설명
Potassium oxalate, K2C204, H20, is odorless, efforescent, water-soluble, colorless crystals that decompose when heated. Sinks in and mixes slowly with water. Used in analytical chemistry and photography, and as a bleach and oxalic acid source.
공기와 물의 반응
Water soluble.
반응 프로필
Potassium oxalate 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.
위험도
Toxic by inhalation and ingestion.
건강위험
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.
화재위험
Behavior in Fire: Loses water at about 160° and decomposes to carbonate with no charring. The reaction is not hazardous.
