Answer: Stock nomenclature of [tex]NH_4NO_3[/tex] is ammonium(I) nitrate
Explanation:
Stock nomenclature is used for chemical nomenclature where the oxidation states of some or all of the elements in a compound are indicated by Roman numerals in parentheses.
For example:
[tex]FeCl_2[/tex] which has iron in oxidation state of +2 has stock nomenclature of iron(II) chloride.
[tex]FeCl_3[/tex] which has iron in oxidation state of +3 has stock nomenclature of iron(III) chloride.
Thus the stock nomenclature of [tex]NH_4NO_3[/tex] is ammonium(I) nitrate as ammonium has oxidation state of +1.
