Question

Identify what is oxidized, reduced, and spectator ion in the reaction of: silver nitrate solution & copper solid.

Reduced :
Oxidized :
Spectator :

Answer 1

Molecular equation is:
2AgNO3(aq) + Cu(s) ==> 2Ag(s) + Cu(NO3)2(aq)
Net ionic equation is:
2Ag^+(aq) + Cu(s) ==> 2Ag(s) + Cu^2+(aq)

Reduced : gain of electrons is reduction
Oxidized : loss of electrons is oxidation
Spectator : nitrate ion
Each Ag goes from 1+ to zero
Each Cu goes from zero to 2+
