The cell \( \mathrm{Pt}\left|\mathrm{H}_{2}(1 \mathrm{~atm})\right| \mathrm{H}^{+}(\mathrm{pH}=\mathrm{x}) \| \) Normal calomel electrode has an EMF of \( 0.67 \mathrm{~V} \) at \( 25^{\circ} \mathrm{C} \). Calculate the \( \mathrm{pH} \) of the solution. The oxidation potential of the calomel electrode on hydrogen scale is \( -0.28 \mathrm{~V} \).
