Question

State Henry’s law correlating the pressure of a gas and its solubility in a solvent and mention two applications of the law.

Answer 1

Answer: Henry's law states that at a constant temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the gas over the solution

Answer 2

Answer:

It states that at constant temperature the mass of a gas(m) dissolved in a given volume of the liquid is directly proportional to the pressure of the gas (P) present in equilibrium with the liquid. (i) To increase the solubility of CO2 in soft drinks and soda water, the bottle is sealed under high pressure. (ii) To minimize the painful effects accompanying the decompression of deep sea divers, oxygen diluted with less soluble helium gas is used as breathing gas.
