WebApr 2, 2024 · This is how we find the lattice energy of calcium chloride by using Born-Haber cycle. Note : We can also use another method to find out the lattice energy of a compound. This method is by using the Born-Lande Equation, given by. L a t t i c e E n e r g y = N A × M × z + × z − × e 2 4 π ε o r ( 1 − 1 n) Where N A is the Avogadro number.

Pure calcium chloride, however, is only available in smaller quantities from chemical reagent supply houses. Commercial grades of calcium chloride, such as those Webtable also displays the standard enthalpy of solution at 25°ë for calcium chloride taken from the handbook [7]. The discrepancy (~2%) may be due to the different purities of the reagents and the different extrapolations to infinite dilution, although the second factor is less significant. It follows that the transition of calcium onr pbgc
