Consider two solutes, Solute A and Solute B, that have the same lattice energy. Both solutes dissolve exothermically in water, but Solute A creates weaker ion-dipole intermolecular forces with water. Which solute has a more exothermic dissolution overall?

Consider two solutes, Solute A and Solute B, that have the same lattice energy. Both solutes dissolve exothermically in water, but Solute A creates weaker ion-dipole intermolecular forces with water. Which solute has a more exothermic dissolution overall

Answer:

Solute B has a more exothermic dissolution

Explanation:

Since Solute A and Solute B have same lattice energy but solution A has a weaker ion-dipole intermolecular forces with water which is the solvent

Solution B will dissolve faster due to higher ion-dipole intermolecular force compare to solution B, in the process of dissolve release energy to it solvent.

Therefore Solute B has a more exothermic dissolution
