Respuesta :

the charge of the irons in each compound is different. The roman numeral shows that iron (ll) nitrate contains Fe2+ ions while iron (lll) nitrate contains Fe3+ ions 

Answer:

The difference between iron (II) nitrate and iron (III) nitrate: difference in oxidation states of iron in both compounds.

Explanation:

1) Iron(II) nitrate :

In iron(II) nitrate , iron is present in the +2 oxidation state.The molecular formula is given as:

[tex]Fe(NO_3)_2[/tex] = ferrous nitarte

2) Iron (III) nitrate

In iron(II) nitrate , iron is present in the +3 oxidation state.The molecular formula is given as:

[tex]Fe(NO_3)_3[/tex] = Ferric nitrate
