# What is Henry Law of solubility?

## What is Henry Law of solubility?

Henry’s law is a gas law which states that at the amount of gas that is dissolved in a liquid is directly proportional to the partial pressure of that gas above the liquid when the temperature is kept constant.

What is the mathematical expression of Henry’s Law?

P=KHX.

Why is Henry’s law important?

The main application of Henry’s law in respiratory physiology is to predict how gasses will dissolve in the alveoli and bloodstream during gas exchange. The amount of oxygen that dissolves into the bloodstream is directly proportional to the partial pressure of oxygen in alveolar air.

### What is the similarity between Raoult law and Henry law?

The similarity between the Raoult’s law and Henry’s law is that both laws state that the partial pressure of the volatile component is directly proportional to its mole fraction in the solution. In case of Raoults’s law it is a liquid and in case of Henry’s law it is a gas.

What is Raoult’s law used for?

Raoult’s law is used to determine the vapor pressure of ideal solutions with nonvolatile solutes based on the vapor pressure of the solvent and the mole fraction of the solvent.

What is the importance of Henry’s Law?

Henry’s law constant is very much important in environmental chemistry, atmospheric chemistry, waste water treatment. They are needed since solubility affects volatilizations of toxic compounds into the air.

#### Who discovered Henry’s law?

chemist William Henry
Henry’s law, statement that the weight of a gas dissolved by a liquid is proportional to the pressure of the gas upon the liquid. The law, which was first formulated in 1803 by the English physician and chemist William Henry, holds only for dilute solutions and low gas pressures.

What is Rahul slaw?

Raoult’s law states that a solvent’s partial vapour pressure in a solution (or mixture) is equal or identical to the vapour pressure of the pure solvent multiplied by its mole fraction in the solution.

What is Roult’s law explain?

What is Raoult’s Law? Raoult’s law states that a solvent’s partial vapour pressure in a solution (or mixture) is equal or identical to the vapour pressure of the pure solvent multiplied by its mole fraction in the solution. Mathematically, Raoult’s law equation is written as; Psolution = ΧsolventP0solvent.

## What is Raoult’s Law example?

Suppose we contain 100 mL of water and 100 mL of ethylene glycol in two different containers. If the vapor pressure of pure water is 500 mmHg, we would like to calculate the new vapor pressure of the solution that is made by mixing the two substances together. This a direct application of Raoult’s law.

What is Henry Law of solution?

Henry’s law, statement that the weight of a gas dissolved by a liquid is proportional to the pressure of the gas upon the liquid. The law, which was first formulated in 1803 by the English physician and chemist William Henry, holds only for dilute solutions and low gas pressures.

What are Henry components?

We designate the higher concentration component as the solvent. The universal validity of Henry’s law as a low-concentration approximation has a simple physical interpretation. The solute vapor pressure depends upon the net effects of solute–solute, solute–solvent, and solvent–solvent intermolecular forces.
