Ammonium Oxalate – 500 gram Packs

Ammonium Oxalate is an inorganic ammonium salt of oxalic acid, commonly identified as diammonium oxalate, with the chemical formula (NH₄)₂C₂O₄ and a molecular weight of approximately 124.10 g/mol. It is generally encountered as a white, odourless crystalline solid that dissolves in water and provides ammonium and oxalate ions for suitable chemical investigations. Ammonium Oxalate is widely relevant to analytical chemistry, qualitative inorganic analysis, and educational laboratory experiments involving precipitation reactions and metal-ion identification. It can be used in appropriate procedures for studying calcium ions through the formation of sparingly soluble calcium oxalate. The reagent is also useful in selected research applications involving oxalate chemistry and aqueous solution preparation. Its suitability for a particular method depends on the chemical form, reagent specifications, and experimental requirements. Careful handling is important because ammonium oxalate can be harmful if swallowed or absorbed through the skin and may cause serious eye irritation.

Frequently Asked Questions About Ammonium Oxalate

What is Ammonium Oxalate used for in laboratories?

Ammonium Oxalate is used in qualitative inorganic analysis, precipitation reactions, and experiments involving oxalate and metal ions. A common application is the identification of calcium ions through calcium oxalate formation. It can also be used to prepare oxalate-containing reagent solutions for suitable analytical and research procedures.

What are the molecular formula and molecular weight of Ammonium Oxalate?

Anhydrous Ammonium Oxalate has the molecular formula (NH₄)₂C₂O₄, equivalent to C₂H₈N₂O₄, and a molecular weight of approximately 124.10 g/mol. The monohydrate contains one additional water molecule and has a formula mass of approximately 142.11 g/mol, so the exact chemical form matters.

What is the CAS number of Ammonium Oxalate?

The CAS Registry Number for anhydrous diammonium oxalate is 1113-38-8. Ammonium Oxalate Monohydrate has a different CAS number, 6009-70-7. Checking the CAS number and hydrate form helps ensure that the selected reagent matches the formula and molecular weight required for the intended laboratory procedure.

How does Ammonium Oxalate help identify calcium ions?

Oxalate ions react with calcium ions in suitable aqueous conditions to form calcium oxalate, a sparingly soluble white solid. The resulting precipitate can provide qualitative evidence of calcium under an appropriate analytical procedure. Other ions and solution conditions may interfere, so validated methods should be followed.

How should Ammonium Oxalate be stored and handled safely?

Store Ammonium Oxalate in a tightly closed, compatible container in a cool, dry location. Wear suitable gloves, protective clothing, and safety goggles, and avoid inhaling dust or contacting the skin and eyes. The substance can be harmful if swallowed or absorbed through the skin. Consult the current Safety Data Sheet for detailed precautions.

Storage Conditions for Ammonium Oxalate

Store Ammonium Oxalate in a tightly closed, compatible container in a cool, dry, well-ventilated area at the recommended ambient temperature. Protect it from contamination and excessive moisture, and keep it away from incompatible materials, including strong oxidizing agents. Close the container promptly after dispensing and follow the product-specific storage instructions in the current Safety Data Sheet.

Precautions for Handling Ammonium Oxalate

Review the current Safety Data Sheet before use and wear suitable chemical-resistant gloves, protective clothing, and safety goggles. Avoid generating or inhaling dust and prevent contact with the eyes and skin. Use adequate ventilation when weighing the powder or preparing solutions. Do not mix it with incompatible chemicals, and follow approved spill-response and waste-disposal procedures. Collect oxalate-containing waste according to institutional requirements and ensure appropriate supervision in educational laboratories.
