State Henry's Law and list some of its important Applications.
Answers
Explanation:
According to Henry's law, the solubility of a gas in a liquid is directly proportional to the pressure of the gas.
Important applications of Henry's law:
1) In packing of soda cans: Soda water bottles are always packed under higher pressure to increase the solubility of CO2 gas.
2) In deep-sea diving: Nitrogen is more soluble than Helium in our blood. In the deep sea, the pressure is higher than at the surface of the water. When diver tries to come rapidly towards the surface of the water, pressure decreases and dissolved nitrogen comes back from blood and makes bubbles in veins. Hence, divers use oxygen diluted with helium.
Answer:
Applications of Henry's law:
(1) To minimise the painful effects accompanying the decomposition of deep sea divers, oxygen diluted with less soluble helium gas is used as breathing gas.
(2) To increase the solubility of CO2 in soft drinks and soda water, the bottle is sealed under high pressure
