Data
The first column contains Henry's law solubility constant
${H}_{\mathsf{s}}^{\mathrm{cp}}$
at the reference temperature of 298.15 K.
The second column contains the temperature dependence
$d\; ln{H}_{\mathsf{s}}^{\mathsf{cp}}/\; d\; (1/\mathsf{T})$, also at the
reference temperature.

Notes
99) 
Fast, irreversible hydrolysis is assumed, which is equivalent to an infinite effective Henry's law constant. 
142) 
Robinson et al. (1997) assumed that the entropy of vaporization is the same for HOCl and ClNO_{3} according to Trouton's rule. On their page 3592, they mention a value of 7 M atm^{−1} at 250 K. However, checking their Fig. 9 and applying the temperaturedependence equation from their Table 3, it seems that the value of 7 M atm^{−1} refers to 298 K, not 250 K.
