Manganese nitrate, with the CAS registry number 10377-66-9, is an inorganic compound with formula Mn(NO₃)₂. This chemical is soluble in water. You should keep it in a cool, dry, dark location and in a tightly sealed container or cylinder. In addition, you must keep it away from incompatible materials, ignition sources and untrained individuals. This chemical has the IUPAC Name of Manganese(2+) dinitrate and EINECS registry number 233-828-8. The substance is white crystalline solid which is denser than water. 

Properties: Manganese nitrate may ignite on contact with organic matter. The anhydrous nitrate salt with urea explodes upon heating. Manganese nitrate is solble in water and ethanol. When heating will separate out manganese dioxide with nitrous oxide gas.

Preparation: Manganese nitrate can be prepared from MnO₂ and nitrogen dioxide. It can also be prepared by dissolving manganese(II) carbonate in dilute nitric acid.

MnCO₃ + 2 HNO₃ → Mn(NO₃)₂ + H₂O + CO₂

Additionally, it is produced from MnO₂ and carbon to give manganese monoxide. And then reacts with hydrogen nitrate. The mixture is purified, concentrated and crystallize to form Manganese nitrate.

MnO₂ + C → MnO + CO
CO + MnO₂ → MnO + CO₂
MnO + 2 HNO₃ → Mn(NO₃)₂ + H₂O

Besides, manganese metal reacts with hydrogen nitrate to produce Manganese nitrate. This method can prepared high purity product.

Mn + 2 HNO₃ → Mn(NO₃)₂ + H₂↑

Uses: It is useful precursors to the oxides of manganese. In addition, it can be used as reagent and oxidant to trace analysis and determine. Manganese nitrate is used for the preparation of electronic components. It can be used for the phosphorus treatment of metal surface. Besides, this chemical is also used to make other chemicals.

When you are using Manganese nitrate, you should be very cautious about it. It is irritating to eyes, respiratory system and skin. In case of contact with eyes, you should rinse immediately with plenty of water and seek medical advice. Whenever you will use or contact it, you need wear suitable protective clothing.
