Abstract:

The hydrolysis equilibria of InIII were studied at 25C in the ionic medium 3 MNaCl- by measuring the hydrogen ion concentration with a glass electrode. The InIII ranged from 0.001 to 0.04 M, and the hydrogen ion concentration was varied from values high enough for the hydrolysis to be negligible to those low enough for a precipitate to be formed. Comparison with the equilibrium constants for the formation of the species InOH2 and InOH24 in 3 MNaCl4- indicates that in 3 M NaCl- medium the species denoted by the collective formulas InOH2 and InOH24 are in reality mainly mixed Cl--OH- complexes just as In3 denotes mainly Cl- complexes.
