The dissolution of calcium chloride in water 2+ CaCl2 (s)- Ca²+ (aq) + 2 Cl(aq) is a spontaneous process at 25°C, even though the standard entropy change of the preceding reaction is negative (AS° = -44.7 J/K). What conclusion can you draw about the change in entropy of the surroundings in this process?
