Not all of them do. Water is a highly polar solvent. Water molecules can interact strongly with ions, forming a shell around them that also screens the ions from each other. An ionic compound will dissolve readily if the interaction energy between the ions and water is energetically (what physicists call the free energy) favorable compared to the solid salt. 1.5k Views Â· View Upvoters
Water-soluble compounds when dissolved in water may dissociate into ions. Compounds that dissociate completely (only ions are present in solution) are called strong electrolytes. Compounds that dissociate partially (both molecules and ions are present in solution) are called weak electrolytes.
