Consider the following standard reduction potentials in acid solution:
Al3+(aq) + 3 e- → Al(s)
AgBr(s) + e- → Ag(s) + Br-
Sn4+(aq) + 2 e- → Sn2+(aq)
Fe3+(aq) + e- → Fe2+(aq)
E° = -1.66 V E° = +0.07 V E° = +0.13 V E° = +0.77 V
The strongest oxidizing agent among those shown above is:
A. Fe3+
B. Fe2+
C. Br-
D. Al
E. Al3+
