Is the dissolution of sodium acetate trihydate endothermic?

For anhydrous sodium acetate 2 3 2, the lattice energy is actually smaller than the hydration energy. The molar enthalpy of solution is negative; at it is .* Thus, the process of dissolving anhydrous sodium acetate in water is exothermic. However, hydration of ions can also occur in crystalline solids.
