Question

question 1 of 30 which of the following is most easily reduced? click for a reduction potential chart a. ag+ b. zn+ c. mg2+ d. fe2+

Explanation:

Step1: Recall reduction potential concept

Higher reduction potential means easier to be reduced.

Step2: Check standard reduction potentials

From standard reduction - potential tables, the reduction potential of $Ag^+$ is relatively high compared to $Zn^+$, $Mg^{2 + }$, and $Fe^{2+}$. The standard reduction potential of $Ag^+ + e^-
ightarrow Ag$ is $E^0 = 0.80\ V$, for $Zn^+ + e^-
ightarrow Zn$ is around $E^0=- 0.76\ V$, for $Mg^{2+}+2e^-
ightarrow Mg$ is $E^0=-2.37\ V$, and for $Fe^{2+}+2e^-
ightarrow Fe$ is $E^0=-0.44\ V$.

Answer:

A. $Ag^+$
