An oxalate (also ethanedioate) is a salt or ester of oxalic acid. As a salt, the oxalate anion has the chemical formula C2O42- or (COO)22-
Consumption of oxalates (for example, the grazing of animals on oxalate-containing plants such as greasewood), or human consumption of Sorrel may result in kidney disease or even death due to oxalate poisoning.
The charge on oxalate allows it to act as a chelator of various positively charged metal ions.
Much of its other properties resemble oxalic acid.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from incompatible substances. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product. Practice good personal hygiene and wash thoroughly after handing material. Do not eat, drink, or smoke in the workplace.
Ventilate area of leak or spill. Keep unnecessary and unprotected people away from area of spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Pick up and place in a suitable container for reclamation or disposal, using a method that does not generate dust.
Inhalation: inhalation of dust is corrosive to mucous membranes. Oxalates can be absorbed through the lungs. Symptoms of poisoning include nervousness, cramps, central nervous system depression.
Ingestion: mean lethal dose for oxalates in adults is estimated at 15-30 grams with death within a few hours or even minutes. Corrosive action on the mucosa and severe gastrointestitis can occur with pain, vomiting, etc. Sharp reduction of serum calcium can cause disfunction of the brain. Calcium oxalate may be deposited in the kidneys.
Skin contact: corrosive. Symptoms of redness, pain, and severe burn can occur.
Eye contact: corrosive. Contact can cause blurred vision, redness, pain and severe tissue burns.
Chronic exposure: circulatory failure or nervous system irregularities may follow prolonged calcium metabolism disturbances due to oxalation.
Cobalt oxalate is highly insoluble in water and converts to the oxide when heated (calcined). Cobalt Oxalate is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards.
It has chemical formula K2C2O4.
Titanium Potassium Oxalate
Ti2(C2O4)3·10H2O Toxic, yellow prisms soluble in water, insoluble in alcohol; used to make titanic acid and titanium metal. Also known as titanous oxalate.
Disodium oxalate, often called simply sodium oxalate, is a sodium salt of oxalic acid with the molecular formula Na2C2O4. It is usually a white, crystalline, odorless powder, that decomposes at 250–270 °C.
Causes severe irritation and burns. May Be harmful if swallowed. Avoid breathing vapor or dust. Use with adequate ventilation. Avoid contact with eyes, skin, and clothes. Wash thoroughly after handling. Keep container closed.
