Manganese(II) hydroxide is obtained as a white precipitate by adding a solution of sodium or potassium hydroxide to a solution of manganese(II) salt, such as manganese(II) chloride ... [Pg.548]

Also, careful dehydration of manganese(II) hydroxide, Mn(OH)2, under controlled conditions in the absence of air yields MnO. [Pg.549]

Aqueous solution of manganese(ll) sulfate undergoes double decomposition reactions precipitating insoluble manganese(II) salts for example, adding caustic soda solution precipitates manganese(II) hydroxide. [Pg.557]

The oxidic catalysts used in this study are prepared as follows. a-MogO is prepared hy thermal decomposition of manganese(II)hydroxide in air at T = 390 K The hydroxide is precipitated from manganese(II)nitrate (Mn(N03>2.4 HjO, Merck) solution with ammonia at pH = 9. Y-F6203 is prepared by oxidation of FejO at 350 K in oxygen (Air Products). a-Fe203 is prepared by thermal decomposition of iron(II)hydroxide in air at T = 875 K The hydroxide is precipitated from iron(IIl)nitrate (Fe(N03)2.9 HgO, J.T. Baker Chemicals B.V.) in the same way as manganese(II)hydroxide. [Pg.489]
