| Apr 10, 2021 at 14:48 | comment | added | Ashish | Okay I understand that's probably the reason for my confusion. But then in a nutshell if someone was to ask me the relation of solubility with henry's constant what would my answer be | |
| Apr 10, 2021 at 14:42 | comment | added | Poutnik | There is more H constants there, with explicit superscript indexes, aside of K_H. The question is not, when to use which equation, but when to use which symbol and constant. | |
| Apr 10, 2021 at 14:34 | comment | added | Ashish | @Poutnik Also incase that the symbols are different it would great if you could explain me the use case of both the expressions ? Like in what cases do we use expression 1 and in what expression 2. | |
| Apr 10, 2021 at 14:33 | comment | added | Ashish | @Poutnik Wikipedia mentions $H = \frac{x}{p}$ where x is the molar mixing ratio. I assume that they mean that x is the mole fraction. But isn't this formula different that what is used otherwise like in here chemistry.stackexchange.com/a/29118/106010 | |
| Apr 10, 2021 at 14:22 | comment | added | Poutnik | It cannot be proportional to p ( in lower letter ) for the same molar fractions and at the same time reciprocal to p for the same concentrations. As concentrations are not reciprocal to molar fractions. See en.wikipedia.org/wiki/Henry%27s_law for different used symbols. | |
| Apr 10, 2021 at 14:11 | comment | added | Ashish | @Poutnik google search of henry's law constant gives me that expression. Also I think I've read it elsewhere too. But as mentioned earlier I am not sure about this topic so it would be good if you could correct me wherever you think I am going wrong | |

| Apr 10, 2021 at 14:06 | comment | added | Poutnik | kh in 1. is not the kh from the Henry law, but rather a solubility constant at given partial pressure. There should be used a different symbol for that. Note that the Henry constant uses the capital K. | |
