Examples of Trioxonitrate 5

Answer 1

Trioxonitrate 5 makes no sense to me. If you mean the nitrate ion, it is [NO3]^- and examples would be
KNO3 which is potassium nitrate.
NaNO3 which is sodium nitrate.
HNO3 which nitric acid.
Al(NO3)3 which is aluminum nitrate
Zn(NO3)2 which is zinc nitrate
etc.
