The plot of solubility of some salts against temperature is given on the right. A salt like NaCl can be recovered fully, when dissolved in a solvent and the solvent is removed by evaporation. Choose the correct statement(s).

Options

  1. ANo heat is absorbed or released when NaCl is dissolved in water.
  2. BMore heat is released when the ions of Yb ₂ ( SO ₄ )₃ are solvated than that absorbed when the ions are separa
  3. CThe heat of solution is negative for H ₃ BO ₃ .
  4. DWhen AlCl ₃ is dissolved in water and the water is evaporated, solid AlCl ₃ is recovered.

Correct answer

B. More heat is released when the ions of Yb ₂ ( SO ₄ )₃ are solvated than that absorbed when the ions are separa
