Who invented Henry’s Law?

Asked by: Lindsey Anderson

chemist William HenryWilliam Henry, holds only for dilute solutions and low gas pressures.

Who came up with Henry’s law?

William Henry

In 1803, William Henry published in the Philosophical Transactions of the Royal Society of London his article on the solubility of gases in water (1). His experiments established the law, now known as Henry’s law, that the solubility of a gas is proportional to the pressure of the gas.

What is Henry’s theory?

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 Henry’s Law?

Henry’s law states that the concentration of a dissolved gas is directly proportional to the partial pressure of that gas above the solution: (18.12)

What is Henry’s Law for Dummies?

Henry’s Law says that because a liquid is in contact with a gas, that gas will dissolve into the liquid. The higher the pressure of the gas, then more gas will dissolve. That’s how your lemonade becomes fizzy, pressurised carbon dioxide has dissolved into the lemonade!

When was the Henry Law discovered?

1803

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.

Which gas does not follow Henry Law?

Examples of gases that do not obey Henry’s law include ammonia, hydrogen sulfide, and hydrogen halides like hydrochloric acid.

Which is an application of Henry Law?

Applications of Henry’s law
Henry’s law in Carbonated soft drinks – When soft drinks bottle is opened some of the gas escapes giving a specific pop. this is due to the lower pressure above the liquid and carbon dioxide comes out as bubbles.

What is the significance of Henry Law constant?

The higher the value of Henry’s law constant KH at a given pressure, the lower is the solubility of the gas in the liquid. Therefore, Henry’s law constantly plays an important role in atmospheric chemistry, environmental chemistry and wastewater treatment plants.

What is the unit of Henry Law constant?

We know the unit of pressure P is \[atm\]and the unit of solubility of the gas at a fixed temperature\[mol/d{m^3}\]. Thus, the unit of Henry’s constant is $mol\,d{m^ – }^3at{m^{ – 1}}$.

What is Henry’s law class 12?

Henry’s law
According to the law at a constant temperature, thesolubility of a gas in a liquid is directly proportional to thepressure of the gas. It can also be stated as – The partial pressure of the gas in vapour phase (p) is proportional to the mole fraction of the gas (x) in the solution.

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.
