$\mathop {{H_2}(Pt)}\limits_{1\,atm} \left| {\begin{array}{*{20}{c}}
{H_{aq}^ + }\\
{pH = 4}
\end{array}} \right|\left| {\begin{array}{*{20}{c}}
{A{g^ + }}\\
{xM}
\end{array}} \right|\begin{array}{*{20}{c}}
{Ag}\\
{}
\end{array}$
What is the value of $x$ ? ........... $\mathrm{M}$
( give : $E_{A{g^ + }|Ag}^o = + 0.8$ $\frac{{2.303\,RT}}{F} = 0.06 $)
$\mathop {Ca{C_2}}\limits_{\left( A \right)} \xrightarrow{{{H_2}O}}B\xrightarrow[{HgS{O_4}}]{{{H_2}O,{H_2}S{O_4}}}C$
