Assign oxidation states to the species in the unbalanced redox reaction. Ag+(aq)+Cu(s)⟶Ag(s)+Cu2+(aq)

Question

Ag+(aq):

Ag(s):

Cu(s):

Cu2+(aq):

Which substance gets oxidized?

Which substance gets reduced?

Balance the redox reaction.

Answer 1

Ag+(aq) + Cu(s) ===> Ag(s) + Cu2+(aq)

1+................0...................0.............2+..........oxidation states

Which substance gets oxidized? Cu goes from 0 to 2+ so it lost 2 electrons and was oxidized

Which substance gets reduced? Ag goes from 1+ to 0, so it gained an electrons and was reduced

Balance the redox reaction.

2Ag⁺(aq) + Cu(s) ==> 2Ag(s) + Cu²⁺(aq) ... balanced equation
