Answer:

In English it's a lot easier than in Dutch.
(e.g. we have to go from "zwavel" to "sulfaat")

Explanation:

You memorize the elements. Then take the central element in the ion, strip off the suffix and add "-ate" or " ite".
So #C#=carbon becomes #CO_3^(2-)# carbonate
and #Si#=silicon becomes #SiO_3^(2-)# silicate

-ate or -ite?
The -ite has one oxigen atom less than the -ate
Sulfate #SO_4^(2-)# vs sulfite #SO_3^(2-)#

But:
It can get even worse. See the following line-up:
#ClO^-# hypochlorite
#ClO_2^-# chlorite
#ClO_3^-# chlorate
#ClO_4^-# (hy)perchlorate
But you see the -ite/-ate rule still stands, just needed some extension.
