Solutions

Expert Solution

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.
