What is the coefficient for #H^+# when the redox equation below is balanced?
#?Ag(s) + ?NO_3^(-)(aq) + ?H^(+)(aq) -> ?Ag^(+)(aq) + ?NO(g) + ?H_2O#
As usual we write separate redox reactions:
And so, we add
This is balanced with respect to mass and charge, so it is reasonable.
The nitrate anion is in fact a potent oxidant; however, in aqueous solution, often its reactivity is kinetically hindered.
