Type: MCQ-diagram based-Hard-Class 11
Imagine a diagram depicting the enthalpy change during the dissolution of an ionic compound in water. Which component of the enthalpy change is directly associated with the energy required to separate the ions in the solid lattice before they interact with water molecules?
A
Lattice enthalpy
B
Enthalpy of hydration
C
Enthalpy of solution
D
Standard enthalpy of formation
Correct Answer
Option A
Detailed Explanation
Lattice enthalpy refers to the energy required to separate ions in the solid lattice, a critical step before the hydration process in solution. This is distinct from hydration or solution enthalpies.
