» Common Manganese compounds:
• Manganese(IV) Oxide, MnO2
• Manganese(II) Oxide, MnO
• Manganese(III) Oxide, Mn2O3
• Manganese(III) Sulfate, Mn2(SO4)3
• Manganese(II) Phosphate, Mn3(PO4)2
• Potassium Permanganate, KMnO4
• Permanganic Acid, HMnO4
• Manganic Acid, H2MnO4
Example Reactions:
• 2Ca + MnO2 = 2CaO + Mn
• MnO2 + 2Mg = Mn + 2MgO
• 2HCl + Mn + 2HNO3 = MnCl2 + 2NO2 + 2H2O
• MnO2 + C = Mn + CO2
• Mn + 2H2O2 = MnO2 + 2H2O
• Mn + 2CuCl = 2Cu + MnCl2
• Mn + 2HCl = MnCl2 + H2
• Mn + 2Cl2 = MnCl4
• 4NaI + 2H2SO4 + MnO2 = 2I2 + Mn + 2Na2SO4 + 2H2O
• K + Mn + 2O2 = KMnO4
