• Melting point: The dihydrate loses its crystalline water at 101-102°C and converts 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), with higher solubility in hot water. Ethanol: slightly soluble (approx. 5.7g/100 mL, 20°C)
• Acid: Binary acid, stronger than acetic acid (pKa₁=1.25, pKa₂=4.14); reacts with bases, metal oxides, carbonates to form salts.
• Reducibility: Under acidic conditions can be oxidized by strong oxidants to produce CO₂ and H₂O
• Complexation: Oxalate (C₂O₄²⁻) forms soluble complexes with metal ions (e.g. Fe³+, Al³+), used in metal cleaning or rust removal.
• Thermal decomposition: Decomposes when heated above 150°C, producing CO, CO₂ and H₂O.
