Question
Based on the following electrochemical data, which is the strongest oxidizing agent?
Hg2+(aq) + 2e → Hg(1)
E°red = +0.85 V
Cr20-2 (aq) + 14H*(aq) + 6e¨
→ 2Cr³+(aq) + 7H2O(1I)
E°red = +1.33 V
Ca2+(aq) + 2e → Ca(s)
E°red = -2.76 V
Zn2+(aq) + 2e → Zn(s)
E°red = -0.76 V
%3D
NO3 (aq) + 4H*(aq) + 3e¯ → NO(g) + 2H2O(1)
E°red = +0.96 V
O A) Zn2+
B) Zn(s)
C) Cr20-²-
D) Ca2+
E) NO3
F) Ca(s)
