Hanson, D. and Mauersberger, K. (1988). Solubility and equilibrium vapor pressures of HCl dissolved in polar stratospheric cloud materials: ice and the trihydrate of nitric acid. Geophysical Research Letters 15: doi: 10.1029/88GL03939. issn: 0094-8276.

Measurements of the pressure-solubility behavior of HCl in water ice and in the nitric acid trihydrate (NAT) crystal at 200 K are reported. It was found that HCl is about 20 times more soluble in NAT than in ice for stratospheric conditions. A relation between HCl pressure and substrate composition based on the Gibbs-Duhem equation is developed. This relation, along with other thermodynamic data, can be used to obtain the HCl pressure-solubility behavior at different temperatures. Implications of these results for the south polar ozone hole are discussed. ¿ American Geophysical Union 1988
