Question

What is the difference between Henry’s law and Raoult’s law?

Answer 1

Hint: Both Henry’s law and Raoult’s law are used to specify the chemical behavior of solutions when it is in contact with vapour pressure. Mainly a solution contains two components and that is solute and solvent. The component which is present in smaller particles is known as solute and the component present in larger particles is known as solvent.

Complete answer:
We have to know that Henry's law and Raoult’s law indicate the chemical behavior of solutions. But it has some differences and that is,
Henry's law states that, the amount of the dissolved gas present in a liquid is proportional to the pressure of the gas. But Raoult's law states the partial pressure of each component present in an ideal mixture of liquid is equal to the mole fraction which is multiplied by the vapour pressure.
Henry's law is appropriate for ideal gases. But Raoult's law is relevant for the solutions.
Henry's law is equivalent to Henry’s constant. But Raoult's law is equal to the vapour present in the pure component.
And Henry's law states the partial pressure of particles with low concentration. But Raoult's law expresses that the pressure of a component with concentration is almost equal to pure liquid.

Note:
We need to know that Henry's law applies only for the ideal gases but Raoult's law will apply to all the solutions. The solution is mainly divided into two types according to the number of components present in the solution and that is, binary mixture and tertiary mixture. If the homogenous mixture contains only two components, which is known as binary mixture.
