WebIf you compare iron to zinc, I think the products produced would similarly depend on the concentration of nitric acid. These could range from NO, NO2, iron(III)nitrate and ammonium nitrate and an oxide coating (Fe2O3) of iron ( in the case of concentrated acid, creating passivity as a direct result of the oxidizing ability of nitric acid).
