At 298 K, the EMF of the cell \[ \mathrm{pt} \mid \mathrm{H}_{2}(1\,\mathrm{bar}) \mid \mathrm{H}^{+}(\text{solution}) \| \mathrm{Cl}^{-} \mid \mathrm{Hg_2Cl_2}\mathrm{Hg} \]
is 0.7530 V. The standard potential of the calomel electrode is 0.2802 V. If the liquid junction potential is zero, the pH of the solution is: (a)4.7
(b)7.4
(c)8.0
(d)12.7
