Product Description

Oxalic acid is an organic substance, chemical form is C2H2O4 . It is a metabolite of living organisms. It is a moderately strong acid. It is widely distributed in plants, animals, and fungi, and performs different functions in different living organisms. Studies have found that more than 100 kinds of plants are rich in oxalic acid, especially spinach, amaranth, beet, purslane, taro, sweet potato and rhubarb and other plants have the highest content. Because oxalic acid can reduce the bioavailability of mineral elements, it is easy to form calcium oxalate with calcium ions in the human body and lead to kidney stones, so oxalic acid is often considered as an antagonist for the absorption and utilization of mineral elements. Its anhydride is carbon sesquioxide.

The main applications of Oxalic acid include cleaning or bleaching, especially for the removal of rust (iron complexing agent). Its utility in rust removal agents is due to its forming a stable, water-soluble salt with ferric iron, ferrioxalate ion. Oxalic acid is an ingredient in some tooth whitening products. About 25% of produced oxalic acid will be used as a mordant in dyeing processes. It is also used in bleaches, especially for pulpwood, cork, straw, cane, feathers, and for rust removal and other cleaning, in baking powder, and as a third reagent in silica analysis instruments.
Oxalic acid can be used to clean minerals like many other acids. Two such examples are quartz crystals and pyrite.
it is also widely used as a wood bleach, most often in its crystalline form to be mixed with water to its proper dilution for use, also in electronic and semiconductor industries.
