Question

$KCl$ easily dissolves in water because:

• A. It is a salt of potassium
• B. It reacts with water
• C. It gets hydrolyzed by water
• 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 molecule and these ions remain separate and dissolved in water. Hence, $KCl$ easily dissolves in water.
