How do ferrous ions, hydrogen ions and nitrate ions react

3Fe2++NO3-+4H+==3Fe3+NO+2H2O

Reaction of Ferrous Ion with Hydrogen Ion and Nitrate Ion Its redox reaction

2Fe2++2H++NO3-=2Fe3++H20+NO2
Ferrous ion hydrogen ion nitrate ion trivalent iron ion water nitrogen dioxide
Nitric acid oxidizes the divalent iron ions to the positive trivalent, and the reduced product is nitrogen dioxide
This is a rule! )
