Consider the following statements:
(I) Solubility depends on lattice enthalpy of the salt and solution enthalpy of the ions.
(II) For a salt to be able to dissolve in a particular solvent its solvation enthalpy must be lesser than its lattice enthalpy.
(II1) In case of non ‐ polar solvents, solvation enthalpy is not small and it is sufficient to overcome the lattice enthalpy of the salt. Thus, salt is able to dissolve in non ‐ polar solvents. Which of the following is incorrect?
Text Solution
Verified by ExpertsB
For a salt to be able to dissolve, its solvation enthalpy should be greater than its lattice enthalpy. As in non ‐ polar solvents, solvation energy is small, it does not overcome the lattice enthalpy, so the salt is unable to dissolve in non ‐ polar solvents.
