Potassium chloride is useful in treating afflictions such as high blood pressure, but is normally prescribed in specific dosages. The body normally regulates its potassium level and keeps it within a narrow range. Natural potassium deficiencies are rare and often occur after dieting, fasting, dehydration and bouts of diarrhea. Natural sources of potassium such as fruits and vegetables are much more efficient sources of potassium. For instance a banana contains approximately 500 milligrams of potassium or roughly five times the amount contained in one tablet.
Consuming excessive potassium chloride can irritate the linings of the stomach and the mouth. Excessive concentrations of potassium in the blood can lead to abnormal muscle actions, renal failure and cardiac arrest in severe cases.
Potassium chloride is sold in pellet form as a water softener by hardware stores such as Home Depot and Ace Hardware stores, and at discount retail stores such as Sam’s Club. The pellets are a sodium-free alternative to softening water and release up to 20 percent less chloride into the environment than traditional sodium chloride water softeners.Learn more about Chemistry
