In line with our practice elsewhere [3], these A(XR) values are rounded to the nearest 0.05. Afterwards we go on to set out the regularities in logK that are newly apparent, and speculate on how these may possibly be extrapolated to some nearest-neighbor compounds. It also needs to be pointed out that Eq. (12.1) as it stands is inadequate for coping with two other situations that in which no common cation is present, or may not be and that in which there is more than one. The first is touched on in Section 12.5.3, while the second is exemplified by the complexities attached to the tautomerism of 2-phthalazinone 39 and analyzed in Sections 12.3.6 and 12.4.1. We end with an Overview. 

Man is a pattern-making animal, and anything that can help to make his patterns more accurate should be welcome to him. 

This is mostly straightforward. In water, with which we shall mostly be concerned, UV measurement is chiefly used [4], commonly at moll at which
