Detailed Solution

Statement - I is true & Statement - II is false
The solubility of NaCl does not change appreciably with increase in temperature
→ Hydration enthalpy of NaCl is -784.0KJ/mole,
Where as lattice enthalpy of NaCl is + 788.0KJ/mole
Since ΔH_solution of NaCl is +4.0Kj/mole,i.e., ΔH_solution value is negligibly small and hence no effect of temperature on its solubility.
→ Common salt [NaCl] generally associated with impurities like MgCl₂ & CaCl₂ .Due to the presence of CaCl₂ & MgCl₂ it behaves as deliquescent.
But the pure form of NaCl [Without MgCl₂ , CaCl₂] Can't shows deliquescent nature as its hydration energy is low due to its large size
