colorless transparent crystal, often containing two molecules of crystal water. When heated to 98-100 °c, the oxalate hydrate loses water of crystallization. Anhydrous oxalic acid is a colorless and odorless solid with deliquescence, and has two crystal forms of rhomboid and monoclinic. At room temperature, the rhomboid oxalic acid crystals are thermodynamically stable, while the monoclinic oxalic acid crystals are thermodynamically metastable. The melting point and density of rhombohedral oxalic acid crystals are slightly higher than that of monoclinic oxalic acid. Anhydrous oxalic acid melting point 189.5 C (decomposition). Partial decomposition begins at 157 °c I formic acid, carbon monoxide and water are formed when oxalic acid is completely decomposed upon accelerated heating. Soluble in water and alcohol, slightly soluble in ether, insoluble in benzene, chloroform and petroleum ether. In case of high heat, open flame or contact with oxidant, there is a risk of combustion. Toxic gases are generated by thermal decomposition.
