TaigaDissolution of gases in water is usually exothermic because the strong intermolecular forces in water (hydrogen bonding) help stabilize the solute molecules in the solution, releasing energy in the form of heat. The breaking of intermolecular forces within the gas molecule and the formation of new intermolecular forces with water leads to a lower energy state, resulting in an exothermic process.

Does the solubility of gases increase with temperature increase?
Yes, the solubility of gases generally decreases with an increase in temperature. This is due to the fact that as temperature rises, the kinetic energy of gas molecules also increases, making it easier for them to escape from the liquid.
What is always in the air?
Oxygen, nitrogen, and various other gases are always present in the air. These gases are essential for supporting life on Earth.
Why are the rates of diffusion of nitrogen gas and carbon monoxide are almost identical at the same temperature?
The densities of these gases are virtually identical.
What are the solute and solvent both gases?
When both the solute and solvent are gases, the solute is the gas that is being dissolved, and the solvent is the gas in which the solute is dissolved. An example is the dissolution of carbon dioxide (solute) in water vapor (solvent) to form carbonated water.
Which gases are released during dissolution of brass?
When brass is dissolved in acid, the gases released may include hydrogen gas (H2) and potentially carbon dioxide (CO2) if carbonates are present in the brass alloy. The exact composition of gases released can vary depending on the specific acid and composition of the brass.
