The Complex Solubilities of Silver Halides in Acetone-Water Mixtures.

摘要

The over-all formation constants and solubility products for the silver chlorides, bromides, and iodides have been determined at 25 C in acetone-water mixtures of the following weight per cent acetone: 80.03, 91.23, and 98.53. In the concentration ranges studied, values of Beta 2 and Beta 3 corresponding, respectively, to the formation of AgX2(-) and AgX3(-2) (X = Cl, Br, I) could be determined. AgX3(-2) decreases rapidly as the water content is increased. Log k(s0) (solubility product) and Log Beta 2 values for pure acetone were evaluated by an extrapolation procedure and the results are compared to previous work. (Author)
