Metaoxyacids
A metaoxyacid is an acid related to oxoacid. Like oxoacids, metaoxyacids share a few similarities. Specifically they:
- contains oxygen;
- contains at least one other element;
- has at least one hydrogen atom bound to oxygen; and
- forms an ion by the loss of one or more protons.
However, they are distinguished in that metaoxyacids:
- have a distinct, differing molecular structure from all oxoacids
- dissolve in a dissimilar manner
- are more stable and do not disperse in aqueous solutions
Generally, oxoacids are simply polyatomic ions with a hydrogen cation, and a metaoxyacid is similar but less reactive.
