Question

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.

Options

  • \[\ce{HCHO < CH4 < CO2 < Ar}\]

  • \[\ce{HCHO < CO2 < CH4 < Ar}\]

  • \[\ce{Ar < CO2 < CH4 < HCHO}\]

  • \[\ce{Ar < CH4 < CO2 < HCHO}\]

MCQ

Solution

\[\ce{Ar < CO2 < CH4 < HCHO}\]

Explanation:

The higher the value of KH, the lower is the solubility of the gas in the liquid. Hence the order of increasing solubility of the gases will be \[\ce{Ar < CO2 < CH4 < HCHO}\]
