प्रश्न
Explain the following phenomena with the help of Henry’s law.
Feeling of weakness and discomfort in breathing at high altitude.
उत्तर
At high altitudes, partial pressure of oxygen is less than that of ground level. This leads to low concentrations of oxygen in blood and tissues of people living at high altitudes or climbers. The low blood oxygen causes climbers to become weak and unable to think clearly known as anoxia.

KH value for \[\ce{Ar(g)}\], \[\ce{CO2(g)}\], \[\ce{HCHO (g)}\] and \[\ce{CH4(g)}\] are 40.39, 1.67, 1.83 × 10–5 and 0.413 respectively. Arrange these gases in the order of their increasing solubility.
Assume that argon exerts a partial pressure of 6 bar. Calculate the solubility of argon gas in water. (Given Henry’s law constant for argon dissolved in water, KH = 40 k bar)
Henry's constant (in k bar) for four gases α, β, γ and δ in water at 298 K is given below:
| α | β | γ | δ | |
| KH | 50 | 2 | 2 × 10-5 | 0.5 |
(density of water = 103 kg m-3 at 298 K)
This table implies that:
