Solubility of Gases in Water: Part 1 Campbell Tip of the Month
1/1/2021· Table 1. Composition of gas mixture. We obtained the solubility of each component in water from ProMax [3] using the Peng-Robinson equation of state. Four isotherms of 5°C, 10°C, 20°C, and 30°C (41°F, 50°F, 68°F, and 86°F) were selected. For each isotherm, the pressure was varied from 200 kPa to 8000 kPa (29 psia to 1160 psia).

Why does butane not dissolve in water? - Quora
There’s nothing for the semi-positive and semi-negative ends of water to match up with, no energy is released, and the butane won’t dissolve. Think about it this way: longer chain hydrocarbons are like oils and, as you know, oil and water don’t mix (at least without some other help). OK, that’s a pretty simplified answer, Bhavin.
