Oxalic acid Purity ≥ 99.6% CAS NO 6153-56-6

Oxalic acid, with the chemical formula H2C2O4, is a common organic acid. It is a colorless crystalline solid, soluble in water, and highly acidic. Oxalic acid is widely used in chemical laboratories and has some applications in industrial production.

Oxalic acid is a strong acid that reacts with water to form an oxalic acid solution. Oxalic acid solution is acidic and can react with alkali to form salt and water. This acid-base reaction is often used in neutralization reactions in chemical laboratories and can also be used in acid-base neutralization processes in industrial wastewater treatment.

Oxalic acid can also form oxalates with metal ions. Oxalate is a common salt compound, such as calcium oxalate (CaC2O4), ammonium oxalate (NH4HC2O4), etc. These oxalates have certain stability and can be used as analytical reagents in chemical laboratories and as raw materials in industrial production.

 Oxalic acid can react with some oxidants, such as hydrogen peroxide (H2O2), potassium permanganate (KMnO4), etc., to cause reduction reactions. This reduction reaction is often used in analytical methods in chemical laboratories, such as the oxalic acid method to determine the content of oxidants. Oxalic acid has several other applications. Oxalic acid can be used as a chelating agent for certain metals, forming stable complexes. Oxalic acid can also be used to clean and remove rust from metal surfaces.

Oxalic acid also has some dangers. Oxalic acid solids and concentrated oxalic acid solutions are irritating to skin and eyes and direct contact should be avoided. Oxalic acid is also a toxic substance and should be stored and used properly to avoid accidental ingestion or inhalation.

Oxalic acid is a common organic acid with strong acidity and reducing properties. It is widely used in chemical laboratories and can be used for acid-base neutralization, preparation and analysis of oxalates, reduction reactions, etc.
