Values for the solubility products, KS0, the enthalpies of solution, ?solH�, and the equilibrium products for AgXi(i-1)- silver halide complexes,�i, of the silver halides in three non-aqueous solvents: methanol, acetonitrile and dimethylsulfoxide, and in their aqueous mixtures, are reviewed.The solvent systems provide examples for three types of mixed aqueous solvent system: aqueous alcohol mixtures and aqueous mixtures with dipolar aprotic solvents that are weakly or strongly basic. As is clear from the figures, the solubilities depend on both the concentration and nature of the organic co-solvent. It can also be seen that variations in the solution enthalpies don't simply mirror those in the solubility products. The data are discussed in terms of solvent � solute and solvent � solvent interactions present in the systems.
