Oxalate – In 1776, the first test of oxalate research done by a scientist named Carl w. Scheele by performing the oxidation of sugar along with nitric acid. In 1784, have proved that this is no oxalate in plant sorrel. In the year 1829, Gay Lussac scientists find results, that it can be produced by doing fused alkali soluble on the sawdust.
It is a derivative of a carboxylic acid containing two carboxyl group in the end of the straight chain of carbon, has a chemical formula or molecular C2H2O4 has no color and odorless, crystalline form have molecular weight about 90 grams/Mole.
What is the function of oxalate?
The function of oxalate is one of the raw materials in need of industrial products, which has other benefits such as:
- Protective coatings for metallic materials, so as not to peel
- To bleching or excess alkali neutralizer in a wash
- Including material that mixes the substance dyes on textile and paint industry
- Including the initiator against plant polymers.
There is another function of the other, namely oxalate:
Determine the amount of calcium
It can form neutral salts with metals alkali metals, where it has a solubility in water of about 5-25%, while for alkali soils have metal solubility in water is so small. Thus, calcium oxalate will not dissolve in water. That’s the reason why it can be used in determining the amount of calcium, the reason is because of the nature of it.
Precipitates of calcium
With the high oxalate found in products that can be utilized in the calcium precipitates, which calcium was added with other products. If there are no conditions on the calcium that is added then it could affect the toxin.
Reduce the increase of the weight
It benefits can this be used in weight loss. Because its react together to form a calcium compound is not soluble and can not be absorbed by the body. So, help in reducing weight.
