    Another question...what does a chemical name actually mean?

    I.e. You could have -sulphide or -sulphate.
    You could have -nitrate, -nitroxide, -nitrogen oxide.

    Does it mean, if it is -ate, it has oxygen added? I don't understand! It's my chemistry exam tomorrow!!

    Help!!

    Sulphides are those containing just sulpher - e.g. Barium sulphide, BaS

    Sulphates are those containing SO3 2-
    Nitrates are those containg NO2 - or NO3 -

    Nitroxides i think are those containing any of the nitrogen oxides like NO, NO2 or NO3

    And nitrogen oxide is just plain old nitrogen and oxygen like NO, NO2 or NO3

    I think if something ends in 'ate' it's an ion like sulphate ion, nitrate ion, chlorate ion

    Hope that helps!
