Oxalic acid is an organic compound with the formula C2H2O4. It is a white 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 agen and its conjugate base, known as oxalate, is a chelating agent for metal cations.
Applications:
1. 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.
2. Oxalic acid is used by some beekeepers as a miticide against the parasitic varroa mite.
3. Oxalic acid is used to clean minerals.
4. 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.
5. Oxalic acid is an ingredient in some tooth whitening products.
