Abstract: The soly. of SO₂ in 0.5, 1.0, 1.5, and 2.0% solns. of NH₃ at 15°, 20°, 25°, and 30° was measured. After the conversion of NH3 into NH₄HSO₃, the soly. of free SO₂ is governed by Henry's law. The soly. of the free SO₂ in dild. solns. of NH₄HSO₃ is lower than its soly. in H₂O. With increasing concn. of NH₄HSO₃ the soly. decreases to a min. and with a further increase of concn. it is increased.
