Question
Given that EoK+/K = - 2.93V; EoFe2+/Fe = - 0.44V ; EoZn2+/Zn = - 0.76V ; EoC+2/Cu = 0.34V;
Based on this Data, which of the following is the strongest reducing agent ?
Based on this Data, which of the following is the strongest reducing agent ?
Options
A.Cu(s)
B.K+(aq)
C.Zn2+(aq)
D.Fe(s)
Solution
K+(aq) and Zn2+(aq) can not lose electron (s). Fe has greater tendency to lose electrons than Cu.
[EFe/Fe2+ = 0.44V > ECu/Cu2+ = - 0.34V]
[EFe/Fe2+ = 0.44V > ECu/Cu2+ = - 0.34V]
