Zn2+(aq) + 2e ⇋ Zn(s); - 0.762 V
Cr3+(aq) + 3e ⇋ Cr(s); - 0.740 V
2H+(aq) + 2e ⇋ H2(g); 0.00V
Fe3+(aq) + e ⇋ Fe2+(aq); 0.770V
Which is the strong reducing agent?

Which is the strong reducing agent?
Options
A.Zn(s)
B.Cr(s)
C.H2(g)
D.Fe3+(aq)
Solution
Since oxidation potential of Zn highest hence it is strongest reducing agent.
