Hi!

I am looking for some data regarding hydrogen solubility in water. Temperature range: 100-200C, pressure range: 30-50bar. This data is missing in CRC handbook. The only thing I found is an article but I do not understand two things, maybe somebody can help:

1) What is internal pressure of a gas in liquid? For example: lim(f_g/N_g)=P_in.t*K_p*K_T, where P_in.t=P_vg+P_in is the internal pressure in liquids (theoretical), K_p is a correction coefficient for pressure, K_T is a correction coefficient for the temperature.
2) What measure unit is cm^3/g (dissolved hydrogen/water)?

I can send the article.

I would appreciate any kind of help, I have no idea where to look for these values.

One more thing: the values in the article mentioned above are theoretical values. I would need empirical concentrations.
