    • H = 7.89 ± 0.13 (average of the values listed in refs. 47b and 47c for 25 °C and I = 0.1-0.5 M), hence, the difference amounts to 0.38 ± 0.13 pK units in good agreement with the estimate given above

    • a value is the average of the constants given in ref. 60a and 60b, i.e., of 10.98 ± 0.02 and 11.05, respectively; to the latter value slightly less weigth is attributed and the error limits are estimated to be ±0.05.

    • NHO 92.4 ± 4.2%. It is evident that this result is not much different from the one given in the text, which we consider as the more reliable one, but in any case it confirms that the formation degree of the "chelate" is large.
