Abstract
THE STABILITY constants for the complexes of 8-hydroxyquinoline-5-sulphonic acid (oxine sulphonic acid) have recently been compared with those for 8-hydroxyquinoline (oxine). For any given metal, the reported difference between corresponding constants was large (up to 10,000-fold) and a plausible explanation was offered1. However, the comparison is not valid because the values for the sulphonic acid were determined in water and those of the 8-hydroxyquinoline in 70 per cent dioxan2.
