What factors determine the enthalpy of solution of an ionic compound?

Options

  1. AThe color of the solute and the solvent.
  2. BThe size of the solute particles.
  3. CThe lattice enthalpy and the enthalpy of hydration of ions.
  4. DThe temperature of the solvent.

Correct answer

C. The lattice enthalpy and the enthalpy of hydration of ions.

Step-by-step solution

The enthalpy of solution of an ionic compound is determined by the lattice enthalpy (∆ lattice H) and the enthalpy of hydration of ions (∆ hyd H).
