    Do you know what Hess' law is?
    It is a logical extension of the law of conservation of energy.

    BH cycles are the application of Hess' law to ionic systems.

    The process defined as formation enthalpy is broken down into several energy steps.

    You then have a cycle in which:

    formation enthalpy = all of the other steps.

    Here's an example using magnesium chloride:
