Manganous dihydrogen phosphate, often represented by the chemical formula Mn(H2PO4)2, is a chemical compound composed of manganese (Mn), hydrogen (H), phosphorus (P), and oxygen (O). It’s an inorganic salt that’s commonly used in various industrial applications.

Manganous dihydrogen phosphate can be prepared by reacting manganese(II) carbonate or manganese(II) hydroxide with phosphoric acid:

MnCO3 + 2H3PO4 → Mn(H2PO4)2 + CO2 + 2H2O

Or

Mn(OH)2 + 2H3PO4 → Mn(H2PO4)2 + 2H2O

This compound has applications in areas such as:

  1. Chemical Industry: It can be used as a source of manganese in the production of other manganese compounds.
  2. Phosphating Agent: It’s utilized in the phosphating process, where metal surfaces are treated with a phosphate coating to improve corrosion resistance, paint adhesion, and lubrication.
  3. Fertilizers: Manganese is an essential micronutrient for plants. Manganous dihydrogen phosphate can be used in fertilizer formulations to provide manganese to plants.
  4. Catalysis: Compounds containing manganese are sometimes used as catalysts in various chemical reactions.
