+1 O => per-ate
-1 O => -ite
-2 O => Hypo-ite
Binary acidsAll have hydrogen on left-hand side (HI (aq))
Remember to add "(aq)" subscript to indicate that it is in an aqueous solution
TO NAME: hydro + element abreviation + ic + " acid"
OxyacidsH + polyatomic ion that contains oxygen with prefixes.
Oxyacid prefixes+0 O => -ic
