Yep, just a hint, not intended to answer the main point you were researching... which I see is now available below, cool! This is because extra oxygen atoms draw away electron density due to their electronegativity, making surrounding atoms more positive, which makes it easier for them to release protons (which are also positive; opposites attract; likes repel). Observe for example the contrast between hypochlorous acid, H-O-Cl, and sodium hydroxide, H-O-Na. first symbol of the ligand formula or ligand abbreviation (see Section IR-4.4.4) as written.

Section IR-4.4.2.1. symbol is closest to the symbol of the central atom to which it is attached. Finally (barring annoying extra rules for isotopes and hydration), we have what are called "generalized salts". If the compound is a coordination compound, we order central atoms by pseudo-electronegativity, and ligands by alphabetical order, as written (eg $\ce{(en)}$ before $\ce{(dmg)}$, but $\ce{C2H4(NH2)2}$ after $\ce{(dmg)}$, even though $\ce{(en)}$ and $\ce{C2H4(NH2)2}$ are the same).

For one, there are actually two ordering standards--one is the extremely boring alphabetical one, which I've never seen used (except in emperical formulae), and one is via electronegativity. Arsenous Acid H3AsO3 Molar Mass, Molecular Weight. Still have questions? Arsenic acid is the chemical compound with the formula H 3 AsO 4. The rules are as follows (source): This leads to the following "pseudo-electronegativity" order of elements: The motivation behind this must probably be the erratic and hard-to-quantify nature of "real" enectronegativity. $\ce{As(OH)3}$ reveals the structure, $\ce{H3AsO3}$ doesn't.
