Comments

The IUPAC recommendation for a table of numbers is for each quantity heading to be "quantity/dimension"

T Delta S in the last column.

When quoting equilibrium constants the IUPAC recommendation in the Compendium of Analytical Nomenclature is to specify the equilibrium, as was done in the goldmine, Table 8. This eliminates any possible ambiguity. I hesitated to do that because I thought it would look messy, but it may be better after all. Here is my suggestion, in part:

Compound	Equilibrium	pK_a	ΔH⁰ /kJ mol^-1	TΔS⁰ /kJ mol^-1
AH₃=Citric acid	AH₃ $\rightleftharpoons$ AH₂ ^- + H⁺	3.128	4.07	21.92
	AH₂^- $\rightleftharpoons$ AH ^2- + H⁺	4.76	2.23	29.4
	AH^- $\rightleftharpoons$ A ^3- + H⁺	6.40	-3.38	33.1

B =ammonia	BH⁺ $\rightleftharpoons$ B + H⁺	9.245	51.95	104.7

The same treatment should be accorded to the table of pK values. Petergans (talk) 08:25, 2 August 2008 (UTC)
