Abstract: Soly. of SO2 in aq. solns. of NaHSO3 at 20-90° and the concn. 0.2-2.0N of Na salt were studied. SO2 soly. is governed by Henry's law. The amt. of free SO2 in solns. decreases at low temps. with increasing concn. of Na salt. At higher temps. the curve showing soly. of free SO2 goes through min., and 90° soly. is increased with increasing concn. of Na salt. This anomaly was observed also with NH4HSO3 solns. (Domansky and Rendos, C.A. 52, 5937f). For detn. the method of D. and R. was applied.
