Question

Substances with high lattice energies tend to be less soluble than substances with low lattice energies.On that basis predict the relative aqueous solubility at 20°C,from highest to lowest,of the following ionic compounds: Ce₂(SO₄)₃,K₂SO₄,KBr,NaCl. A)Ce₂(SO₄)₃ > K₂SO₄ > KBr > NaCl B)Ce₂(SO₄)₃ > K₂SO₄ > NaCl > KBr C)KBr > NaCl > K₂SO₄> Ce₂(SO₄)₃ D)NaCl > KBr > K₂SO₄> Ce₂(SO₄)₃

Quizplus · Accepted Answer

Compounds with lower lattice energies are generally more soluble. KBr and NaCl have lower lattice energies compared to K2SO4 and Ce2(SO4)3, making them more soluble. Among the given options, KBr is the most soluble, followed by NaCl, K2SO4, and Ce2(SO4)3.
