Question

explain Henry law and it's aaplication

Answer 1

Hey there!

Henry Law states the solubility of gas in a liquid is directly proportional to the pressure of the gas.

1. In the production of carbonated beverages-in order to increase the solubility of Carbon dioxide in cold drinks,beer etc,the bottle are sealed under high pressure.When the bottle is opened under normal atmospheric pressure,the pressure inside the bottle falls to atmospheric pressure & the excess Carbon dioxide bubbles out of the bottle causing effervescence.

2. At high altitudes-the partial pressure of oxygen at high altitudes is less than the ground level.this results in low concentration of oxygen in the blood & tissues of the peoples

3. In scuba diving- during scuba diving,when the diver breaths in compressed air from the supply tank,more nitrogen dissolves in the blood & other body fluids because the pressure at that depth is far greater than the surface atmospheric pressure.

Answer 2

Hey !!

Question = What is henry 's law and it's Application ?

Answer = It states that at a constant temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the Gas.

→ The most commonly used form of Henry's Law states that the partial pressure of a gas in vapour phase is proportional to the mole fraction of the gas (x) in the solution and is expressed as     

                     P = Kh x                      

Here Kh is the Henry's constant and x is the mole fraction of the gas.

APPLICATIONS OF HENRY'S LAW

• To avoid the toxic effects of high concentration of nitrogen in the blood, the tanks used by scuba divers are filled with air diluted with helium (11.7% helium , 56.2% nitrogen and 32.1% oxygen)
• At high altitudes, low blood oxygen causes climbers to become weak and make them unable to think clearly, which are symptoms of a condition known as anoxia.
• To increase the solubility of CO₂ in soda water and soft drinks, the bottle is sealed under high pressure.
