Question
State Henry’s law. Write its one application. What is the effect of temperature on solubility of gases in liquid?
✓

Answer

Henry’s law states that the mole fraction of gas in the solution is proportional to the partial pressure of the gas over the solution.
Applications: solubility of CO2 gas in soft drinks/solubility of air diluted with helium in blood used by sea divers or any other.
Solubility of gas in liquid decreases with increase in temperature.
