Oxalic acid generally contains two-molecule crystal water, which is colorless and transparent crystal, and its crystal structure has two forms, namely α type (diamond-shaped) and β-type (monoclinic crystal form), and the melting points are respectively, α type: 189.5 °C, β type: 182 °C. Relative density, α type: 1.900, β type: 1.895. The refractive index is 1.540. Oxalic acid begins to sublimate at 100 °C, rapidly sublimates at 125 °C, sublimates in large quantities at 157 °C, and begins to decompose. Soluble in ethanol, soluble in water, slightly soluble in ether, insoluble in benzene and chloroform.
