ACS Grade
Oxalic acid dihydrate

Oxalic Acid, also known as Ethanedioic Acid, Aquisal, Oxiric acid, Oxalic Acid Dihydrate, and Oxalsaeure has the chemical formula C2H2O4. It appears as colorless to white, odorless solid crystals. It is soluble in Water, Ethanol, and slightly soluble in Ether at ambient conditions. It is the conjugate acid of Oxalate that is Ethane substituted by the Carboxyl group at positions 1 and 2. The ACS Grade is generally equivalent to the reagent grade and is acceptable for use in analytical applications and research laboratories.

    About Oxalic Acid

    Oxalic acid is an organic compound with the formula C2H2O4. It is a colorless crystalline solid that forms a colorless solution in water. Its acid strength is much greater than that of acetic acid. Oxalic acid is a reducing agent and its conjugate base, known as oxalate is a chelating agent for metal cations.

    Oxalic acid is an odorless white solid. Sinks and mixes with water. It is a strong dicarboxylic acid occurring in many plants and vegetables. It is produced in the body by metabolism of glyoxylic acid or ascorbic acid. It is not metabolized but excreted in the urine. It is used as an analytical reagent and general reducing agent.

    It occurs naturally in many foods, but excessive ingestion of oxalic acid or prolonged skin contact can be dangerous. Its name comes from the fact that early investigators isolated oxalic acid from wood-sorrel (Oxalis) flowering plants.

    Leafy greens and other plant foods are very popular among the health-conscious. However, many of these foods also contain an antinutrient called oxalate (oxalic acid). Foods high in oxalate include beet greens, rhubarb, spinach, beets, swiss chard, endive, cocoa powder and kale. Oxalic acid is the main acid present in tomatoes. As tomatoe ripens, the amount of Vitamin C decreases and the amount of oxalic acid increases.

    About 25% of produced oxalic acid will be used as a mordant in dyeing processes. It is used in bleaches, especially for pulpwood. It is also used in baking powder and as a third reagent in silica analysis instruments. 
    Oxalic acid's main applications 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 used for extractive metallurgy. It is an important reagent in lanthanide chemistry. Hydrated lanthanide oxalates form readily in very strongly acidic solutions in a densely crystalline, easily filtered form, largely free of contamination by nonlanthanide elements. Thermal decomposition of these oxalate gives the oxides, which is the most commonly marketed form of these elements. Oxalic acid is used by some beekeepers as a miticide against the parasitic varroa mite. Oxalic acid is used to clean minerals. Oxalic acid is sometimes used in the aluminum anodizing process, with or without sulfuric acid. Compared to sulfuric acid anodizing, the coatings obtained are thinner and exhibit lower surface roughness.

    Oxalic Acid Safety And Hazards

    As dust or as a solution, Oxalic Acid can cause severe burns of eyes, skin, or mucous membranes. Ingestion of 5 grams has caused death with symptoms of nausea, shock, collapse, and convulsions coming on rapidly. Repeated or prolonged skin exposure can cause dermatitis and slow-healing ulcers.
