Calculating Enthalpy of Solution We can use a Born-Haber cycle to calculate the enthalpy of solution using an indirect route. This involves breaking an ionic lattice to give gaseous ions (enthalpy of lattice dissociation) and then dissolving these gaseous ions in water (enthalpy of hydration). The equation used to calculate enthalpy of solution ...

Hess's law states that if a process can be expressed as the sum of two or more steps, the enthalpy change for the overall process is the sum of the ΔH values for each step. To use Hess's law, two principles must be understood: one, if an equation is reversed, the sign of the ΔH value is also reversed. Two, if an equation is multiplied by a ...
