Potassium is a mineral used by the body to maintain good health. It is especially important in maintaining a healthy beating heart. Low levels of potassium (hypokalemia) in the body can be caused by certain medicines or from a prolonged sickness associated with vomiting and diarrhea. Hypokalemia is treated with potassium supplements to raise the levels of the mineral in the body.

Sodium chloride is often used to soften and treat water in both residential and commercial settings. Potassium chloride can replace sodium in water softeners, reducing the amount of sodium released into household supplies of drinking water. Using potassium chloride raises levels of potassium in drinking water reducing the risk of hypokalemia. In agricultural settings, potassium in the water supply acts as an important food source for plants and reduces the amount of sodium in the drinking water of animals.

As salt is extremely harmful in excess, potassium is often used as a substitute for sodium. Salt advertised as low sodium is usually a mix of sodium and potassium while salt advertised as sodium-free is commonly made up of potassium chloride. The downside of using potassium chloride as a salt substitute is that it is also harmful when consumed in large quantities. People who suffer from kidney problems can find it difficult to expel large quantities of potassium chloride form their bodies.

Lethal injection is used in many states of the U.S. as a form of capital punishment. Three chemicals are administered in lethal injection executions: sodium thiopental, pancuronium bromide and potassium chloride. Sodium thiopental is used as a fast-acting anesthetic, pancuronium bromide is then administered as a paralyzing agent before potassium chloride is used to stop the heart while producing extreme pain.
