How does the solubility of a gas change with increasing temperature? It increases. It decreases. It is uniform. The temperature
2 answers:
Answer: It decreases.
Explanation: Solubility of gas in a particular liquid is the volume of gas in ml that can dissolve in unit volume of the liquid to form the saturated solution at the given temperature and under a pressure of 1 atmosphere.
Effect of temperature on solubility of gas:
Solubility of gas decreases with increase in temperature as on heating some gas is expelled out of the solution.
According to Le Chateliers principle , on increasing the temperature, the reaction will shift in a direction where temperature is decreasing i.e. backward direction and thus the solubility would decrease.
