Zinc is a solid metal at room temperature, melting point 420 ̊C.
Zinc element is easy to lose 2 eletrons, and becomes Zn2+ ion.
» Common Zinc compounds:
• Zinc(II) Oxide, ZnO
• Zinc Hydroxide, Zn(OH)2
• Zinc Sulfate, ZnSO4
• Zinc(II) Phosphate, Zn3(PO4)2
• Zinc Bromate, Zn(BrO3)2
• Zinc Acetate, Zn(C2H3O2)2
• Zinc Nitrate, Zn(NO3)2
• Zinc Chloride, ZnCl2
• Zinc(II) Carbonate, ZnCO3
Example Reactions:
• Zn + 2HCl = ZnCl2 + H2
• Zn + Pb(NO3)2 = Zn(NO3)2 + Pb
• H2SO4 + Zn = ZnSO4 + H2
• Zn + 2AgNO3 = Zn(NO3)2 + 2Ag
• CuSO3 + Zn = ZnSO3 + Cu
• Zn + Cu(NO3)2 = Cu + Zn(NO3)2
• Mg + Zn(NO3)2 = Mg(NO3)2 + Zn
• ZnO + CO = Zn + CO2
• Zn + 2AgCl = ZnCl2 + 2Ag
• Zn + Cu2SO4 = 2Cu + ZnSO4
