Question

The solubility in water of sulphates down the Be group decreases. This is due to-

• A. high heat of solution for smaller ions like Be²⁺
• B. increasing molecular weight
• C. decreasing lattice energy
• D. increase in melting points.

Answer 1

The correct option is A

high heat of solution for smaller ions like Be²⁺

High heat of solvation for smaller ions like $B{e}^{2+}$
