WebMay 29, 2024 · Solubility = 180 100 g m L − 1. While A g C l has. Δ E N = ( 3.5 − 1.93) = 1.57. Solubility = 0.193 100 g m L − 1. In summary, the solubility of ionic compounds is greater when there is a significant size difference between the ions and when there is a greater difference in their electronegativities. Footnotes. Solvation (specifically, hydration) is important for many biological structures and processes. For instance, solvation of ions and/or of charged macromolecules, like DNA and proteins, in aqueous solutions influences the formation of heterogeneous assemblies, which may be responsible for biological function.
