12.17—Energy cycles and energy level diagrams to calculate the enthalpy change of solution of an ionic compound

Be able to use energy cycles and energy level diagrams to calculate the enthalpy change of solution of an ionic compound, using enthalpy change of hydration and lattice energy.

Use —energy cycles and energy level diagrams to calculate the enthalpy change of solution of an ionic compound to connect the rule to the data and decision in the question.

This matters because —energy cycles and energy level diagrams to calculate the enthalpy change of solution of an ionic compound determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —energy cycles and energy level diagrams to calculate the enthalpy change of solution of an ionic compound to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Energy cycles and energy level diagrams to calculate the enthalpy change of solution of an ionic compound is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
