Enthalpy of Formation. The (molar) enthalpy of formation is the heat released ( ) or absorbed ( ) in a chemical reaction at constant pressure when simple substances combine into a more complex substance. At standard conditions of pressure and temperature (1 atm and 298 K), it is denoted . For elements in their standard states, .
Yes, the enthalpy of hydration is always negative. Hydration enthalpy is the energy released when 1 mol of a substance is dissolved in a solvent. It is always negative, as bonds (e.g. dative, ion-dipole) are being formed. When the solvent is other than water, the process is referred to as solvation. The enthalpy of hydration is equal to the sum of three different energy transfer processes 1  : the lattice energy.  the enthalpy of hydration of the cation.
