WebApr 12, 2016 · Sodium iodide, though, is still more soluble at high temperatures. I could be missing something here, though. In the cases where it is specifically the solvation reaction that causes a temperature change, is it the true that lower temperatures always increase solubility of salts with exothermic solvation reactions (and vice-versa)? WebAbout Transcript For ionic compounds containing basic anions, solubility increases as the pH of the solution is decreased. For ionic compounds containing anions of negligible basicity (such as the conjugate bases of strong acids), solubility is unaffected by changes in pH. Created by Jay.
