Which of the following is true regarding the solubility of a gas in a liquid?
The solubility of a gas in a liquid increases with increasing temperature for all gases.
The solubility of a gas in a liquid decreases with increasing pressure for all gases.
The solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid.
The solubility of a gas in a liquid is independent of the nature of the gas and the liquid.
Henry's Law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. Therefore, option c) is true.
Option a) is not true as the solubility of a gas in a liquid can increase or decrease with increasing temperature, depending on the gas and the liquid. Option b) is also not true as the solubility of a gas in a liquid generally increases with increasing pressure, according to Henry's Law. Option d) is not true as the solubility of a gas in a liquid depends on the nature of the gas and the liquid.
