» Common Mercury compounds:
• Mercury(I) Chloride, Hg2Cl2
• Mercury(II) Oxide, HgO
• Mercury(II) Chloride, HgCl2
• Mercury(I) Oxide, Hg2O
• Mercury(II) Bromide, HgBr2
• Mercury(II) Acetate, Hg(C2H3O2)2
Example Reactions:
• HgO2 = Hg + O2
• Hg2CO3 = Hg + HgO + CO2
• Hg(NO3)2 = Hg + 2NO2 + O2
• Hg + I2 = HgI2
• Hg + NiCl2 = HgCl2 + Ni
• Zn + HgO + H2O = Zn(OH)2↓ + Hg
• Hg2Cl2 = Hg + HgCl2
• HgS + O2 = Hg + SO2
• 2Na + HgBr2 = Hg + 2NaBr
• Hg + 2NH4I = HgI2 + H2 + 2NH3
