Introduction to Oxalic Acid
Oxalic acid is a colorless, crystalline organic compound with the chemical formula C₂H₂O₄. It is a naturally occurring substance found in many plants, such as spinach and rhubarb, and is also produced industrially for various applications.
Key Properties:
  • Appearance: White crystalline solid
  • Solubility: Highly soluble in water and alcohol
  • Acidity: A strong organic acid, capable of forming salts known as oxalates
Industrial Production Methods:
  • Oxidation of Carbohydrates: Using nitric acid as an oxidizer
  • Sodium Formate Method: A widely used industrial process involving carbon monoxide and sodium hydroxide
  • Ethylene Glycol Oxidation: Catalyzed by nitric acid or air
  • Biological Fermentation: Utilizing microorganisms like Aspergillus niger
Applications:
  • Cleaning Agent: Effective in removing rust and stains from metals
  • Bleaching Agent: Used in textiles and wood industries
  • Chemical Synthesis: A key raw material for dyes, pharmaceuticals, and other chemicals
  • Rare Earth Extraction: Essential in separating and purifying rare earth elements
  • Electroplating: Stabilizes metal ions in plating solutions
  • Polishing Agent: Restores shine to marble and stone surfaces
Safety Considerations:
Oxalic acid is toxic if ingested and can cause irritation to the skin and eyes. Proper handling and protective equipment are essential when working with this chemical.
Environmental Impact:
While widely used, oxalic acid is biodegradable and considered environmentally friendly when managed responsibly. Oxalic acid's versatility and effectiveness make it a vital component in numerous industrial and commercial processes.

The Role of Oxalic Acid in Cleaning
  • Remove rust: Reacts with metal oxides to produce soluble compounds, effectively removing rust from iron and steel surfaces. Used for cleaning metal tools, pipes, and machinery.
  • Remove scale: Reacts with calcium and magnesium ions to form soluble salts, removing scale from ceramics, tiles, and glass. Ideal for bathroom and kitchen surfaces.
  • Bleach: Reduces pigment molecules to bleach natural materials like textiles and wood.
  • Decontamination: Decomposes organic stains such as ink, tea, and coffee stains on various hard surfaces.
  • Restore shine: Removes surface oxidation and dirt to restore material luster, particularly effective on stone and metal surfaces.
  • Disinfect: Provides antibacterial properties for cleaning and disinfecting sanitary facilities.
