Question

When potassium chloride (KCl) dissolves in water to form K⁺ and Cl^– ions, the temperature of the solution decreases.

KCl(s) → K⁺(aq) + Cl^–(aq)

Identify which has a higher enthalpy, KCl(s) or the K⁺ and Cl^– ions.

Accepted Answer

K⁺(aq) and Cl^–(aq) ions have higher enthalpy.

Answer

KCl(s) has higher enthalpy.
