Chapter 18, Problem 46E

Interpretation Introduction

Interpretation: The standard cell potential for each of the given electrochemical cells (or reactions) is to be calculated.

${\text{Ni}}^{\text{+2}}\left(\text{aq}\right)\text{+Mg}\left(\text{s}\right)\to \text{Ni}\left(\text{s}\right){\text{+Mg}}^{\text{+2}}\left(\text{aq}\right)$

$\text{2}\text{}{\text{H}}^{\text{+}}\left(\text{aq}\right)\text{+Fe}\left(\text{s}\right)\to {\text{H}}_{\text{2}}\left(\text{g}\right){\text{+Fe}}^{\text{+2}}\left(\text{aq}\right)$

$\text{2}{\text{NO}}_{\text{3}}^{-}\left(\text{aq}\right)\text{+8}{\text{H}}^{\text{+}}\left(\text{aq}\right)\text{+3}\text{Cu}\left(\text{s}\right)\to \text{2}\text{NO}\left(\text{g}\right)\text{+4}{\text{H}}_{\text{2}}\text{O}\left(\text{l}\right)\text{+3}{\text{Cu}}^{\text{+2}}\left(\text{aq}\right)$
