Manganese Oxalate – 500 gram Packs

Manganese Oxalate is an inorganic manganese(II) salt of oxalic acid that contains manganese ions paired with oxalate anions. The anhydrous composition is represented by MnC2O4, although commercial laboratory materials can also occur as hydrates with different formula masses and registry identifiers. This compound is generally encountered as a light-coloured solid with limited water solubility and greater reactivity in suitable acidic media. Its relevance to inorganic chemistry lies in precipitation, coordination chemistry and the conversion of manganese-containing precursors during controlled heating. In teaching and research laboratories, it provides a useful material for discussing metal carboxylates, insoluble salts and chemical transformations. Confirm the exact hydrate form on the supplied label before performing quantitative calculations or setting a preparation method. This listing is for the 500 gram pack size.

Why Choose Lab Wale to Buy Manganese Oxalate

Lab Wale supports procurement of Manganese Oxalate for colleges, universities, research centres and laboratory professionals seeking clearly identified scientific supplies. The 500 gram pack option allows institutions to select a quantity appropriate to their planned work. Before ordering, buyers should review the chemical identity, intended laboratory method, available specification and current safety information. Where hydration, isomerism or an unusual solid phase affects calculations, confirm the exact supplied material. Choose the reagent only when the verified form and laboratory safety controls match the intended application.

Frequently Asked Questions About Manganese Oxalate

Why does manganese oxalate have more than one reported molecular weight?

The anhydrous salt has a formula mass of 142.96 g/mol, but manganese(II) oxalate dihydrate has a mass of about 178.99 g/mol. Water of crystallization changes the amount of manganese in a weighed portion, so the exact form must be identified before quantitative work.

Is manganese oxalate freely soluble in water?

No. Manganese(II) oxalate is poorly soluble in water, and this behaviour is relevant to precipitation and separation experiments. It can react or dissolve differently in acidic media. Solubility should be established for the particular reagent form and experimental conditions.

Can manganese oxalate be used as an oxide precursor?

Yes. Controlled thermal decomposition of manganese oxalate has been studied as a route to manganese-containing oxides. The final phase depends on temperature and atmosphere. Such work requires appropriate heating equipment, ventilation and characterization rather than an assumption of a single product.

Which CAS number applies to manganese oxalate?

CAS 640-67-5 identifies the anhydrous salt, while manganese(II) oxalate dihydrate is commonly listed under CAS 6556-16-7. Because the supplied product name does not specify hydration, the container label or supplier documentation must be checked before choosing a hydrate-specific identifier.

What precautions apply to manganese oxalate powder?

Avoid inhaling dust and prevent contact with the eyes and skin. Wear suitable gloves and eye protection, handle powders with effective ventilation, and follow the current Safety Data Sheet. Collect residues as chemical waste rather than releasing manganese compounds into drains.

Storage Conditions for Manganese Oxalate

Keep manganese oxalate in a tightly closed, chemically compatible container in a cool, dry laboratory storage area. Protect the solid from excessive heat, airborne moisture and contamination. Segregate it from strong oxidizing agents and incompatible reagents. Identify and retain the verified hydrate form on the container label, because changes in moisture content can affect quantitative laboratory use.

Precautions for Handling Manganese Oxalate

Consult the current Safety Data Sheet before handling manganese oxalate. Use laboratory gloves, protective eyewear and suitable protective clothing, and minimize the formation of airborne dust during transfer. Work with appropriate local ventilation, especially when heating the material. Avoid ingestion, skin contact and release to the environment. Manage heated residues and contaminated equipment according to the institution’s chemical-waste procedures.
