Potassium chloride dissolved the most endothermically, and calcium chloride dissolved the most exothermically.
Why do some salts dissolve Exothermically and some dissolve Endothermically?
Dissolution of sodium chloride (table salt) in water is endothermic. ... This is because more energy is released upon formation of solute-solvent bonds than was required to break apart the hydrogen bonds in water, as well as the ionic bonds in KOH.
