Here's why:

* Ionic Compound: Potassium chloride is an ionic compound, meaning it's formed by the attraction between positively charged potassium ions (K+) and negatively charged chloride ions (Cl-).

* Polar Solvent: Water is a polar solvent, meaning it has a partial positive charge on one end of the molecule and a partial negative charge on the other.

* Attraction: The positive and negative charges of water molecules attract the oppositely charged ions in potassium chloride, breaking the ionic bonds and dissolving the compound.

Therefore, potassium chloride readily dissolves in water to form a solution.
