Physicochemical Properties
Molecular weight: 126.07 g/mol
Appearance: White transparent crystal or powder, industrial products may be slightly yellow due to impurities.
Odor: Tasteless or slightly sour.
Density: 1.65 g/cm³ (20°C).
Melting point: The dihydrate lost its crystalline water at 101-102°C and was converted to anhydrous oxalic acid (H₂C₂O₄). Anhydrous oxalic acid sublimates at about 189.5°C and decomposes at high temperatures.
Solubility: Water: soluble in cold water (about 10 g/100 mL, 20°C), hot water solubility is higher. Ethanol: slightly soluble (approx. 5.7g /100 mL, 20°C)
Acid: Binaric acid, acidic stronger than acetic acid (pKa₁=1.25, pKa₂=4.14); It can react with bases, metal oxides, carbonates to form salts (such as sodium oxalate, calcium oxalate).
Reducibility: Under acidic conditions can be oxidized by strong oxidants (such as potassium permanganate) to produce CO₂ and H₂O
Complexation: Oxalate (C₂O₄²⁻) forms a soluble complex with metal ions (e.g. Fe³+, Al³+). It is used in metal cleaning or rust removal.
Thermal decomposition: Decomposition when heated above 150°C, producing CO, CO₂ and H₂O:
