Question

Please give reasons for compounds like silver sulfate or silver chloride to be insoluble that relate to lattice energy versus energy of hydration.

Answer 1

Compounds like silver sulfate or silver chloride are insoluble because the Lattice energy of silver sulfate and silver chloride is much greater than their energy of hydration.

For a compound to be soluble the lattice energy should be less than the energy of hydration, so that tyhe energy of hydration overcomes the lattice energy and the compound becomes solube.
But in case of compounds like silver sulfate or silver chloride, their attice energy is much greater than their energy of hydration that's why they are insoluble compounds.
