Calcium oxalate Chemical Properties,Uses,Production

Description

Calcium oxalate (in archaic terminology, oxalate of lime) is a chemical compound that forms envelope-shaped crystals, known in plants as raphides. A major constituent of human kidney stones, the chemical is also found in beerstone, a scale that forms on containers used in breweries. Its chemical formula is CaC2O4 or Ca (COO)2.

Chemical Properties

colourless crystals

Physical properties

Most crystals look like a 6 sided prism and often look like a pointed picket from a wooden fence. More than 90 % of the crystals in a urine sediment will have this type of morphology. These other shapes are less common than the 6 sided prism, however it is important to be able to quickly identify them in case of emergency.

Occurrence

Many plants are accumulating calcium oxalate (it has been reported in 1000 genera of tree ). The calcium oxalate accumulation is linked to the detoxification of calcium (Ca2+) in the plant.
Calcium oxalate is a poisonous substance that can produce sores and numbing on ingestion and could even be fatal.
The poisonous plant dumb cane (Dieffenbachia) contains the substance and on ingestion can prevent speech and be suffocating. It is also found in rhubarb (in large quantities in the leaves) and in species of Oxalis, Araceae, taro, kiwifruit, tea leaves, agaves, and Alocasia and in spinach in varying amounts. Insoluble calcium oxalate crystals are found in plant stems, roots, and leaves and produced in idioblasts. Calcium oxalate, as ' beer stone ', is a brownish precipitate that tends to accumulate within vats, barrels and other containers used in the brewing of beer.

Application

Calcium oxalate is used in the manufacture of ceramic glazes.

Definition

ChEBI: The calcium salt of oxalic acid, which in excess in the urine may lead to formation of oxalate calculi (kidney stones).

Health Hazard

Even a small dose of calcium oxalate is enough to cause intense sensations of burning in the mouth and throat, swelling, and choking that could last for up to two weeks . In greater doses it can cause severe digestive upset, breathing difficulties, coma or even death. Recovery from severe oxalate poisoning is possible, but permanent liver and kidney damage may have occurred.
The stalks of plants in the Dieffenbachia genus produce the most severe oxalate reactions. The needle - like oxalate crystals produce pain and swelling when they contact lips, tongue, oral mucosa, conjunctiva, or skin. Edema primarily is due to direct trauma from the needle-like crystals and, to a lesser extent, by other plant toxins (e.g., bradykinins, enzymes).
Depending on the plant ingested, mild (Elephant Ear Colocasia esculenta) to more severe (Jack in the Pulpit, Arisaema) can cause compromised airways. One bite on the Arisaema seed pod will result in immediate swelling and burning. It will take over 12 hours for the swelling to subside .
4 – 1 - Treatment
Medication administered at the emergency room may include diphenhydramine, epinephrine, or famotidine, all intravenously. Although this most likely will be a localized reaction, it will be treated by the ER as an anaphylactic reaction.
