Manganese Phosphate is an inorganic orthophosphate salt in which manganese is present primarily in the +2 oxidation state. The ideal anhydrous formula, Mn3(PO4)2, represents three manganese ions associated with two phosphate ions. It is a relatively water-insoluble solid that is relevant to coordination, precipitation and materials chemistry. Hydrated manganese phosphates are also known; their formula masses differ from the anhydrous composition and should not be interchanged without verification. Researchers investigate manganese phosphate compounds as starting materials for phosphate-containing functional solids and surface-treatment chemistry. In colleges and advanced laboratories, the material can support demonstrations of ionic stoichiometry and the behaviour of sparingly soluble phosphates. Selection of a particular hydrate or composition is essential for quantitative and phase-sensitive procedures. This listing is for the 500 gram pack size.

Key Features of Manganese Phosphate
- Contains manganese(II) and orthophosphate units in an ideal 3:2 ionic ratio.
- Low water solubility permits study of phosphate precipitation.
- Useful as a precursor in selected phosphate-material investigations.
- Supports comparisons between anhydrous and hydrated inorganic salts.
- Research applications require matching the phase and hydration state to the method.
Laboratory Applications of Manganese Phosphate
- Studying orthophosphate precipitation reactions in advanced inorganic chemistry.
- Investigating phosphate-based manganese solid phases using diffraction or spectroscopy.
- Exploring manganese phosphate precursors in materials-synthesis research.
- Demonstrating the balance of manganese(II) and phosphate ionic charges.
- Comparing dissolution behaviour of manganese phosphate under different controlled pH conditions.
Why Choose Lab Wale to Buy Manganese Phosphate
Lab Wale supports procurement of Manganese Phosphate 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 Phosphate
What is the formula of manganese(II) phosphate?
The ideal anhydrous composition is Mn3(PO4)2, with a formula mass of approximately 354.76 g/mol. Some manganese phosphate products contain water of crystallization. Their masses and properties must be calculated using the actual hydrate formula shown by the supplier.
Does manganese phosphate dissolve readily in water?
Manganese(II) orthophosphate is only sparingly soluble in water. Its dissolution depends on conditions such as acidity and the solid phase present. This is why manganese phosphate is relevant to precipitation chemistry rather than simply functioning as a highly soluble manganese solution reagent.
Is manganese phosphate the same as manganese hydrogen phosphate?
No. Manganese(II) orthophosphate, Mn3(PO4)2, is distinct from salts containing hydrogen phosphate or dihydrogen phosphate ions. Their chemical formulas, acidity, solubility and registry records differ, so the correct phosphate species should be checked before use.
Why is hydrate information important for this reagent?
Different water contents change the reagent mass required to provide a specified quantity of manganese or phosphate. Some laboratory and materials methods also depend on crystalline phase. Verify the supplied hydrate state before preparing a batch or comparing published experimental results.
How should this manganese salt be handled?
Handle the powder with gloves, eye protection and dust-minimizing procedures. Avoid inhalation and unintended environmental discharge, follow the current Safety Data Sheet, and use suitable containment for research processes that involve acids or elevated temperatures.
Storage Conditions for Manganese Phosphate
Store manganese phosphate in a sealed, clearly labelled container in a dry and well-ventilated reagent cabinet at ordinary laboratory room temperature. Keep it away from unnecessary moisture, strong acids and incompatible materials. Do not heat or dry the solid merely to change its form without checking the intended hydrate and experiment, since the phase can influence analytical results.
Precautions for Handling Manganese Phosphate
Review the current Safety Data Sheet for manganese phosphate and the specific hydrate supplied. Wear protective gloves, eye protection and a laboratory coat; avoid raising dust during weighing. Use adequate ventilation when powder is transferred or treated with acids. Do not discharge manganese-containing residues into drains. Conduct higher-temperature materials research only with suitable ventilation, equipment and trained supervision.
