Question

Which of the following is not a correct statement about enthalpy of solution?

• A. For most ionic compounds, $\Delta H_{so\ln}^{o}$ is positive and the dissociation process is endothermic.
• B. Solubility of most salts increases with increase in temperature.
• C. If the lattice enthalpy is very high, the dissolution of compound becomes very easy.
• D. Enthalpy of solution is determined by the selective values of the lattice enthalpy and hydration enthalpy.

Answer 1

Answer: (C)

If the lattice enthalpy is very high, the dissolution of compound becomes very easy.

Answer 2

: Dissolution of compound may not take palce if lattice enthalpy is very high.
