Manganese(II) nitrate Manganese(II) nitrate Manganese(II) nitrate are the inorganic compounds with formula Mn(NO)(HO). Each formula unit is composed of one Mn cation and two NO anions and varying amounts of water. Most common is the tetrahydrate Mn(NO)·4HO, but mono- and hexahydrates are also known as well as the anhydrous compound. Some of these compounds are useful precursors to the oxides of manganese. Manganese(II) nitrate is prepared by dissolving manganese(II) oxide in nitric acid: It can also be prepared from manganese dioxide and nitrogen dioxide: On heating to 300 °C, aqueous solutions of manganese(II) nitrate thermally decompose to form MnO and NO.

Manganese, Minnesota Manganese, Minnesota Manganese was a small village in Wolford Township, Crow Wing County, Minnesota, United States. Manganese lies roughly north of Trommald, Minnesota. Just off County Road 30, it is perhaps best identified by its location between Coles Lake and Flynn Lake. First appearing in the 1920 census, the village was abandoned by 1960. Named after the mining of its namesake, the village first appeared as "Manganese Village" in the 1920 Census with a population of 183. A post office called Manganese was in operation from 1912 until 1924. Over time, like most other minerals in the Cuyuna Range, all
