Which mixture is used for respiration by deep sea divers?
1 \({\rm{Ne + }}{{\rm{O}}_{\rm{2}}}\)
2 \({\rm{Kr + }}{{\rm{O}}_{\rm{2}}}\)
3 \({\rm{Ar + }}{{\rm{O}}_{\rm{2}}}\)
4 \({\rm{He + }}{{\rm{O}}_{\rm{2}}}\)
Explanation:
Scuba divers must cope with high concentrations of dissolved gases while breathing air at high pressure, underwater. Increased pressure increases the solubility of atmospheric gases in blood. When divers come towards surface, the pressure gradually decreases. This blocks capillaries and creates a medical condition called bends. To avoid bends, the tanks are used by scuba divers that are filled with air diluted with helium (11.7% helium, 56.2% nitrogen and 32.1% oxygen). Thus, option (4) is correct.

Value of Henry’s constant, \({{\rm{K}}_{\rm{H}}}\)
1 Increases with increase in temperature.
2 Decreases with increase in temperature.
3 Remains constant.
4 First increases then decreases.
Explanation:
Value of \({{\rm{K}}_{\rm{H}}}\) depends on temperature and nature of solvent.

Assertion : The solubility of a gas in a liquid increases with increase of pressure. Reason : The solubility of a gas in a liquid is directly proportional to the pressure of the gas.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Henry's law states that the solubility of a gas in a liquid is directly proportional to the gas pressure above the liquid, expressed mathematically as \({\text{x = k P}}\), where ' \({\text{x}}\) ' is solubility, ' \(\mathrm{P}\) ' is partial pressure, and ' \(\mathrm{k}\) ' is the Henry's law constant representing the proportionality between gas solubility and pressure. So option (1) is correct.
