Web7 Nov 2010 · potassium chloride in water is a endothermic reaction.An endothermic reaction is any chemical reaction that absorbs heat from its environment. WebIn the sodium chloride case, you don't have to have very much increase in entropy to outweigh the small enthalpy change of +3.9 kJ mol-1. So . . . does the entropy increase when sodium chloride dissolve in water? Yes, it does! Originally, the sodium and chloride ions were arranged in a very tidy way in the crystal lattice - their entropy was low.
