This seems to be ridiculously hard to research, as Google only wants to give me results about dissolving H2S in water (rather than the other way around)--and when I tried to get around that by looking for information on H2O/H2S phase diagrams, or eutectic mixtures, all I could get was single-substance phase diagrams for one or the other, and information about deep eutectic solvents for H2S scrubbing.

So... does anybody know how soluble water ice is in liquid H2S at -70 to -80 Celsius?

    $\begingroup$ I am curious why you may need that. I assume very few chemists would be willing to measure it. $\endgroup$

    $\begingroup$ @Poutnik Because I am an SF author and it turns out that whether or not ice will dissolve is plot-relevant. (It's the sort of thing Hal Clement might've written, except much better than me.) I would've thought someone would measure on the basis that it'd be relevant to producing pure anhydrous chemicals for industrial purposes. $\endgroup$

    $\begingroup$ I'm sure there is someone somewhere who uses cold H2S, but for typical industrial applications it is liquified by simple compression rather than chilling. If anhydrous is needed, H2O is removed from the gas phase before compression, so there is no need to know anything about the solubility of H2O in cold H2S and therefore not much motivation to measure it. $\endgroup$

    $\begingroup$ I would guess the hydrogen sulfide would rather dissolve into the ice. $\endgroup$
