- Mention some of its important applications. Answer: Henry's law states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas. Further mole fraction of the gas in a solution is proportional to the partial pressure of the gas.
Answer:
In chemistry, Henry's law is a gas law that states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid. The proportionality factor is called Henry's law constant. It was formulated by the English chemist William Henry, who studied the topic in the early 19th century. In his publication about the number of gases absorbed by water.
..."water takes up, of gas condensed by one, two, or more additional atmospheres, a quantity which, ordinarily compressed, would be equal to twice, thrice, &c. the volume absorbed under the common pressure of the atmosphere."
(i) In the production of carbonated beverages (as solubility of CO2CO2 increases at high pressure)
(ii) In the deep sea diving
