Half-cell reaction. From the data above , it can be deduced that the most powerful reducing agent of the four metals is
A.
Cu
B.
Fe
C.
Ba
D.
Zn
Correct answer is C
Elements with lower electrode potentials are most likely to be reduced and act as a reducing agent. Lower electrode potential indicates a greater tendency to accept electrons.
