Exchange and recoil effects in some hexahaloantimonate(V) salts
The original objective of this research was to find out if the hexabaloantimonate (V) salts were suitable for a detailed study of photo-annealing. However, attempts at duplicating some of the early work revealed serious insufficiencies in the analytical procedures used as insufficient attention was paid to the exchange processes, which were studied after the earlier reported work on antimony compounds. The analytical methods used included sulphide precipitation, the use of caesium chloride as a precipitant and the extraction of antimony (V) into di-isopropyl ether from eight molar hydrochloric acid. The dependence of the exchange rate on antimony (V), antimony (III), and hydrochloric acid concentrations was totally ignored in all previous work. Paper chromatography, including the use of paper impregnated with different reagents had been attempted. All these techniques were reinvestigated.
