Question

$KCl$ easily dissolves in water because:

• A. it is a salt of potassium
• B. it reacts with water
• C. it is an electrovalent compound
• D. its ions are easily solvated

Answer 1

The correct option is D its ions are easily solvated

Lattice energy of $KCl$ is less than hydration energy of $K^{+}C{l}^{-}$. $K^{+}$and $C{l}^{-}$get surrounded by water molecules and these ions remain separate and dissolved in water. So, $KCl$ is easily soluble in water.
