Would it be a disambiguation page?

There is no sense in words "hydrogen ion" other than "a ion of (atomic) hydrogen". Had we a dozen of various hydrogen ions, this could become a list, but there are only two distinct scientific objects covered by this name. I will be surprised if someone demonstrates a couple of legitimate links to "hydrogen ion", not created by navboxes or mistakenly pointed here instead of hydron (chemistry).

Diameter

Can the diameter of this ion be determined knowing the diameters of hydronium ion and the geometry of water molecule?--188.26.22.131 (talk) 15:53, 15 April 2011 (UTC)[reply]

"Under aqueous conditions found in biochemistry, hydrogen ions exist as the hydrated form hydronium, H₃O⁺, but these are often still referred to as "hydrogen ions" or even "protons" by biochemists, and they instead use the notation H⁺."

Protonated water isnt just H
₃O⁺
, and who says it just biochemist who calls it protons? (unsourced). Christian75 (talk) 16:36, 29 September 2013 (UTC)[reply]

Shorthand way of thinking, or name?

In addition, the ions produced by the reaction of these cations with water as well as their hydrates are called hydrogen ions:

Hydronium ion: H₃O⁺...

It's totally misleading to say that a hydronium ion is called a hydrogen ion, as if "hydrogen ion" denotes or names hydronium.

The truth is more complicated: people content themselves with an easier, older story involving loose H⁺ 's floating in a soup, because it's a kind of shorthand that works. But no-one forgets the real story once they know it. Rather, they stick to the old notation while actually intending the full picture. This does not mean that a hydrogen ion "is" a hydronium ion. We must be careful not to confuse linguistic shortcuts observed in the community with scientific definitions of entities. Each must be reported but in its own way. 89.217.27.113 (talk) 22:59, 28 January 2015 (UTC)[reply]
