1.	What is the similarity between Raoult’s law and Henry’s law?
Answer» According to Raoult‘s law, the vapour pressure of a volatile componentin a given solution is given by pi = xi pi⁰. In the solution of a gas in aliquid, one of the components is so volatile that it exists as a gas and We have already seen that its solubility is given by Henry‘s law which states thatp = K_Hx. If we compare the equations for Raoult‘s law and Henry‘s law, itcan be seen that the partial pressure of the volatile component or gasis directly proportional to its mole fraction in solution. Only the proportionality constant K_H differs from p1⁰ . Thus, Raoult‘s law becomesa special case of Henry‘s law in which K_H becomes equal to p1⁰.
