$1 \times 10^{-4} \quad 2 \times 10^{-4} \quad 0.1 \times 10^{-4} \quad 0.2 \times 10^{-4}$

(Where $E$ is the electromotive force)

Which of the above half cells would be preferred to be used as reference electrode?

$Ag(s)\,\,|\,\,A{g_2}{C_2}{O_4}(s)\,\,|\,\,{C_2}O_4^{2 - }(0.02\,M)\,\,||\,\,A{g^ + }(0.5\,M)\,\,|\,\,Ag(s)$

$EMF$ of cell is $0.264\ V$ at $25\,^oC$ . $K_{sp}$ of $Ag_2C_2O_4(s)$ is

$\left[ {Given = \frac{{2.303 \times 8.314 \times 298}}{{96500}} = \frac{{2.303RT}}{F} = 0.06,\,\log 2 = 0.3} \right]$
