The enthalpy of solution of NaCl in water is about 3.88 kJ/mol. However, the solubility of NaCl in water is relatively high. Which statement about the entropy of the solution process explains why NaCl dissolves in water even though the process is endothermic?

a. the entropy increases when NaCl dissolves in water
b. the entropy remains the same when NaCl dissolves in water
c. the entropy decreases when NaCl dissolves in water
d. entropy has nothing to do with the solution process

We have that the statement that explains why NaCl dissolves in water even though the process is endothermic the given as,

  • The entropy increases when NaCl dissolves in water.

Option A

Heat

Generally ,Sodium chloride  is crystalline salt, when  its dissolved is H20 , it dissociates its ion, the ions are scattered through out the solution which results in increased  in randomness .

Therefore, the entropy increases when NaCl dissolves in water,

Option A
