Potassium Tetraoxalate (CAS 6100-20-5) is a white crystalline dihydrate salt of oxalic acid, supplied as a crystalline powder or solid that appears white to beige, and it is used in metal surface treatment, electroplating baths, textile processing as a mordant enhancer, and industrial equipment descaling. It acts as a chelating agent for metal ions, derived from oxalic acid neutralization, and is valued for its role in precise analytical calibrations.

Potassium Tetraoxalate

Applications

Utilized in metal surface treatments for oxide removal; in electroplating baths for pH stabilization; in laboratory standards for acid-base titrations; in textile processing as mordant enhancers; and in cleaning solutions for industrial equipment descaling operations.

Safety & Risks

Corrosive nature poses risks of severe eye and skin burns upon contact; ingestion can lead to systemic oxalate poisoning affecting kidneys. Incompatible with strong bases generating heat; mandate acid-resistant PPE and emergency neutralization kits in handling zones per safety data sheets.

Packaging

Housed in 25 kg corrosion-resistant polypropylene containers with child-proof closures. Place in acid storage cabinets with spill trays, ensuring separation from alkaline materials.
