complete equation and net ionic equation:
1. Zn+CuSO4+ZnSO4+Cu
2. 2Zn+Fe(NO3)2=Fe+2Zn(NO3)
3. Zn+SnCl4=4ZnCl+Sn
1) The Chemical equation
CuSO4(aq) + Zn(s) --------> ZnSO4(aq) + Cu(s)
=> This kind of reaction known as displacement reaction where more electropositive metal will displace the less electropositive metals from its salt.
=> From example given, Zn is more electropositive than Cu in
Reactivity Series of metal. So Zn will displace Cu from
CuSO4.
And
Net ionic equation
Cu2+ + Zn ----------> Zn2+ + Cu
Spectator ion: SO4 2‐
Zn metal is oxidized; Cu2+ is reduced.
2) The complete equation is Zn+Fe(NO3)2--------->Fe+Zn(NO3)2
and Net ionic equation is Zn(s) + Fe2+ (aq) -------> Zn2+ (aq) + Fe (s)
Spectator ion: NO3‐
Zn metal is oxidized; Fe2+ is reduced.
3) The complete equation is Zn+SnCl4--------->Sn+ZnCl4
and Net ionic equation is Zn(s) + Sn4+ (aq) -------> Zn4+ (aq) + Fe (s)
Spectator ion: Cl ‐
Zn metal is oxidized; Sn4+ is reduced.
