| Résumé : |
Conductimetric titrations of freshly boiled, concentrated, one-third basic chromium sulphate tanning liquors (S02 reduced dichromate), showed that the average or predominant complex was probably a dimer, in which two chromium atoms are linked in ring formation with two OH groups, and two sulphate groups are bidendately bound to this complex. It was suggested that both of these sulphates formed part of the ring structure, but Slabbert considers this to be unlikely due to the fact that bond angles would be strained. |
