Oxy-acids or oxygen containing acids
They are the non-organic acids containing the element Oxygen.
Mostly can be made of, starting with the right oxyde (like: sulfur trioxyde with water --> sulfuric acid).
these acids can vary in nomenclature, depending on the minimal and maximal number of oxygen atoms in the molecule
(that has to do with the so called oxydation number (see module 10).
So you have H2SO3 and H2SO4
Also the conjugated basesof these acids get an own name.
example:
phosphoric acid = H3PO4. (is made of P2O5 with H2O)
If the formula is not H3PO4, but H3PO3, then this acid is called: phosphorous acid.

N.B.
Not all oxygen containing acids have all four options
But they all have the normal '...ic acid' and '....ate'
Some have also the '....ous acid' and the '....ite'
Hypo and hyper are rather exceptional
