Question
How does solubility of a gas in water varies with the temperature?
Solution
Effect of temperature:
According to Charle’s law, volume of a given mass of a gas increases with increase in
temperature. Therefore, volume of a given mass of dissolved gas in solution also increases with increase in temperature, so that it becomes impossible for the solvent in solution to accommodate gaseous solute in it and gas bubbles out. Hence solubility of gas in liquid decreases with increase of temperature.
