+1.101V
Explanation:
- The 2 ionic half equations of the cell are given below.
Since zinc is more reactive than copper, zinc loses electrons more readily to form#Zn^(2+)# ions.
#Zn (s) -> Zn^(2+)(aq) +2e^-#
#Cu^(2+)(aq) +2e^- -> Cu(s)# - Look up the standard potentials for the half-reactions.
#E^o# for reduction of#cu^(2+)# is +0.339V
#E^o# for oxidation of#Zn# is +0.762V
Cell potential
= +0.339V +0.762V
= +1.101V
