Final answer:
When potassium chloride (KCl) is mixed with water, it dissolves and forms solvated ions.
Step-by-step explanation:
When potassium chloride (KCl) is mixed with water, it dissolves and forms solvated ions. The polar water molecules are attracted to the charges on the K+ and Cl- ions, resulting in the hydration of the ions. This hydration reduces the strong interionic forces that bind the ions together in the solid compound and allows them to move off into solution as solvated ions.
