industries. Lead is poisonous. Lead cations include Pb+2 and Pb+4.
» Common Lead compounds:
• Lead(IV) Nitrate, Pb(NO3)4
• Lead(II) Nitrate, Pb(NO3)2
• Lead(IV) Phosphate, Pb3(PO4)4
• Lead(II) Dichromate, PbCr2O7
• Lead(IV) Oxide, PbO2
• Lead(II) Hydroxide, Pb(OH)2
• Lead(II) Oxide, PbO
• Lead(IV) Hydroxide, Pb(OH)4
• Lead(II) Chloride, PbCl2
Example Reactions:
• Zn + Pb(NO3)2 = Zn(NO3)2 + Pb
• Pb + 2HCl = PbCl2 + H2
• Pb + Cu(NO3)2 = Pb(NO3)2 + Cu
• Ni + Pb(NO3)2 = Ni(NO3)2 + Pb
• Pb + 2AgNO3 = Pb(NO3)2 + 2Ag
• Ca + Pb(NO3)2 = Pb + Ca(NO3)2
• Pb + FeSO4 = PbSO4↓ + Fe
• Zn + PbSO4 = Pb + ZnSO4
• Pb + 2H2SO4 = 2H2 + Pb(SO4)2
• Pb + PbO2 + 2H2SO4 = 2H2O + 2PbSO4↓
