Given : NO_(3)^(-) rarrNO_(2)( acidic medium ), " "E^(-)=0.8V NO_(3)^(-) rarr NO_(3)OH( acidic medium )" "E^(-)=0.74V At what pH the above two half reactions will have same EMF values ? Assume the concentration of all the species to be unity. ( Take 0.059~~0.06)

Given : NO_(3)^(c-) rarrNO_(2)( acidic medium ), " "E^(c-)=0.8V NO_(3)^(c-) rarr NO_(3)OH( acidic medium )" "E^(c-)=0.74V At what pH the above two half reactions will have same EMF values ? Assume the concentration of all the species to be unity. ( Take 0.059~~0.06)

Given : NO_(3)^(c-) rarrNO_(2)( acidic medium ), " "E^(c-)=0.8V NO_(3)^(c-) rarr NO_(3)OH( acidic medium )" "E^(c-)=0.74V At what pH the above two half reactions will have same EMF values ? Assume the concentration of all the species to be unity. ( Take 0.059~~0.06)

NO_(3)^(-) rightarrow NO_(2) (acid medium), E^(@0 = 0.790)V NO_(3)^(-) rightarrow NH_(3)OH^(+) (Acid medium). E^(@) = 0.731V At what pH, the above two will have same E value? Assume the concentration of all other species NH_(3)OH^(+) except [H^(+)] to be unity. (Give your answer by excluding the decimal places).
