Ag+(aq) + Cu(s) → Ag(s) + Cu2+(aq)
Step 1: Separate the whole reaction into two half-reactions
Cu(s) → Cu2+(aq) Ag+(aq) → Ag(s)
Assign oxidation states to all the elements in this unbalanced reaction:
Ag+(aq) + Cu(s) → Ag(s) + Cu2+ (aq)
Which substance gets oxidized?
Which substance gets reduced?
Balance the Redox reaction.
