NO3 is not an acid but would be an acid if it had H(hydrogen) in front of it
To improve on this: NO3- is the conjugate base of HNO3, which is a strong acid. Because the conjugate base of any strong acid is an EXTREMELY weak base, it could for most intents and purposes be considered neutral as it is highly unlikely to significantly raise the pH of a solution.
NO2 is a molecule, not an ion. It is nitrogen dioxide.
However, there is the polyatomic ion NO2- called the nitrite ion. Not to be confused with nitrate (NO3-).
NO3- is the nitrate ion
anion
NO3- is a spectator ion.
Nitrate Ion
The nitrate ion is NO3-
Nitrate ion: NO3-
Nitraite = NO3 One Nitrogen atom (N) Three Oxygen atoms (O3)
You must mean....NO3(-) this is the polyatomic ion nitrate
Nitrate: NO3-
(NO3)-
No3 -
The formula for the nitrate ion is NO3 -1.
The ion nitrate (NO3)- is toxic at higher levels.
NO3 -
