The original version of the article was published in Cent. Eur. J. Chem. 9(3) (2011), pp 391–403. Unfortunately, the original version of this article contains mistakes in the caption of the y-axis of Figs. 5,6 and 10 due to a font conversion problem. The actual units on the y-axis of these figures should be µS cm−1, not mS cm−1.
