1.

Write the overall redox reaction for the zinc-copper cell. Show the oxidation and reduction half reaction.

Answer»

SOLUTION :Overall redox reaction.
`Zn_((s))+Cu_((aq))^(2+) RARR Zn_(aq)^(2+)+Cu_((s))`
oxidation half reaction :
`Zn_((s))+Cu_((aq))^(2+) rarr Zn_(aq)^(2+)+2e^(-)`
REDUCTION half reaction :
`Cu^(2+)+2e^(-) rarr Cu_((s))`
