Question

state henry's law and two important applications

Answer 1

Henry’s law states that the mass of a gas dissolved per unit volume of the solvent at a given temperature is proportional to the pressure of the gas in equilibrium with the solution.

Or

It also states that the pressure of a gas over a solution in which the gas is dissolved is proportional to the mole fraction of the gas dissolved in the solution.

The important applications of Henry’s law are as follows:

1) In the production of carbonated beverages-in order to increase the solubility of CO2 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 CO2 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

Answer 2

this is the Henry law and I don't know two important applications who you help me
