To maximize the solubility of a gas in a liquid, what combination of pressure and temperature is most effective?

💡 Explanation:

The solubility of a gas in a liquid is governed by pressure and temperature. According to Henry's Law, gas solubility is directly proportional to the partial pressure of the gas (high pressure increases solubility). Gas dissolution in liquid is generally an exothermic process, so according to Le Chatelier's principle, an increase in temperature decreases gas solubility (low temperature increases solubility). Therefore, the maximum solubility is achieved with high pressure and low temperature.
