The true statement is the following:
b. In general, the solubility of a gas in water decreases with increasing temperature.
What is solubility?
Solubility can be defined as the solute making a solution with solute.
The solute can be can liquid, solid, or gas, but the solvent is always solid or liquid.
As the temperature rises, the system receives additional energy, which the gas molecules employ to overcome the solvent-gas interactions.
They move free to enter the gaseous state.
Thus, the solubility of a gas in a liquid reduces as the temperature rises. The correct option is b.
