pKa rules

Aren't there also some rules made by Pauling regarding pKa of compounds with double-bonded oxygens attached to them? Would it be worth putting them on this page or a fresh one with a link to it? Brammers (talk) 17:27, 22 February 2009 (UTC)[reply]

I remember these, they're given in N. C. Norman (1997). Periodicity and the s- and p-Block Elements. Oxford: Oxford University Press. p. 76. ISBN 978-0-19-855961-0.

"Trends such as these are embodied in Pauling's rules specifically for the acid O_pE(OH)_q, pK_a = 8−5p"

Also discussed in Greenwood & Earnshaw, 2nd Ed., p. 50.

Yep, the oxoacid rules are actually taught fairly commonly to chemistry undergrads. Might make it myself. — Preceding unsigned comment added by J1812 (talk • contribs) 05:24, 15 February 2013 (UTC)[reply]

Added it in a separate section for now. J1812 (talk) 05:33, 15 February 2013 (UTC)[reply]

But this is a completely different topic which is explained in the article on Acid dissociation constant. Each Wikipedia article should cover a single topic, so I have replaced your section with a hatnote pointing to the detailed article on Ka, for readers who are interested in that topic.

Thanks Dirac. You've done a really good job sprucing up the article! Brammers (talk/c) 10:11, 13 July 2014 (UTC)[reply]

derivation

A derivation of how .225 is the minimum stable radius ratio would be nice. For octahedral, the square root of 3 minus one is = .73205, so it is easy to see why that is the minimum stable radius ratio, but it is not so clear to me for the others. —Preceding unsigned comment added by 24.247.43.141 (talk) 03:42, 19 January 2010 (UTC)[reply]
