The EMF of cell: \( \mathrm{H}_{2}(\mathrm{~g}) \mid \) Buffer \| Normal calomel electrode, is \( 0.70 \mathrm{~V} \) at \( 25^{\circ} \mathrm{C} \), when barometric pressure is \( 760 \mathrm{~mm} \). What is the \( \mathrm{pH} \) of the buffer solution? \( E_{\text {Calomel }}^{\circ}=0.28 \mathrm{~V} \). [2.303 \( R T / F=0.06 \) ]
(a) \( 3.5 \)
(b) \( 7.0 \)
(c) tending to zero
(d) tending to \( 14.0 \)
