Question

The standard reduction potentials at 298 K for the following half reactions are given against each:

Zn2+(aq)+2eZn(s);0.762 V
Cr3+(aq)+3eCr(s);0.740 V
2H+(aq)+2eH2(g);0.00 V
Fe3+(aq)+eFe2+(aq);0.770 V

Which is the strongest reducing agent?

  1. H2(g)
  2. Zn(s)
  3. Cr(s)
  4. Fe3+(aq)

A
Cr(s)
B
Zn(s)
C
H2(g)
D
Fe3+(aq)
Solution
Verified by Toppr

Since oxidation potential of Zn is highest amongst the above given half cell hence it will be strongest reducing agent.
So, option A is correct.
