if sulphate is written as So4 then why nitrate is written as No3?

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
