if sulphate is written as so4 then why nitrate is written as no3 not no4

Expert Answer
Some polyatomic anions contain oxygen which are called oxyanions. If an element forms two oxyanions, then one with less oxygen is given a name ending in -ite and the one with more oxgyen is given a name that ends in -ate.
For example,
NO2- Nitrite
NO3- Nitrate
SO32- Sulphite
SO42- Sulphate
Therefore, sulphate is written as SO4 and nitrate is written as NO3.
