Question

Which of the following statement is incorrect?

• A. Low solubility of LiF in water is due to its small hydration enthalpy.
• B. $KO _2$ is paramagnetic.
• C. Solution of sodium in liquid ammonia is conducting in nature.
• D. Sodium metal has higher density than

Answer 1

Answer: (A)

Low solubility of LiF in water is due to its small hydration enthalpy.

Answer 2

The low solubility of LiF in water is not primarily due to its small hydration enthalpy. Instead, it is primarily due to the strong ionic interaction between lithium and fluoride ions, which makes it difficult for water molecules to break apart the crystal lattice and solvate the ions.

So, the correct option is (A): Low solubility of LiF in water is due to its small hydration enthalpy.
