Chapter 19, Problem 3KSP

Of the following aqueous solutions, identify the one that would yield the smallest mass of metal and the one that would yield the largest mass of metal when it is electrolyzed with a current of 2.00 A for 25 minutes.

$\begin{array}{l}{\text{CuSO}}_{\text{4}}{\text{ AgNO}}_{\text{3}}{\text{ AuCl}}_{\text{3}}{\text{ ZnSO}}_{\text{4}}\text{ Cr}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\hfill \\ \left(\text{a}\right)\hfill \\ {\text{ZnSO}}_{\text{4}}{\text{, CuSO}}_{\text{4}}\hfill \\ \left(\text{b}\right)\hfill \\ {\text{CuSO}}_{\text{4}}{\text{, ZnSO}}_{\text{4}}\hfill \\ \left(\text{c}\right)\hfill \\ {\text{AgNO}}_{\text{3}}\text{, Cr}{\left({\text{NO}}_{\text{3}}\right)}_{\text{3}}\hfill \\ \left(\text{d}\right)\hfill \\ {\text{Cr(NO}}_{\text{3}}{\text{)}}_{\text{3}}{\text{, AuC1}}_{\text{3}}\hfill \\ \left(\text{e}\right)\hfill \\ {\text{AuCl}}_{\text{3}}{\text{, AgNO}}_{\text{3}}\hfill \end{array}$
