Physicochemical property

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:
