Potassium

Symbol: K Melting Point: 146.1 FMolar Mass: 39.0983 Atomic Number: 19

Potassium is a soft silvery-white metal that is highly reactive with water. Potassium is involved in many essentials, including fertilizer, food and in some labratory uses.

It's Essential to our Diet.

Potassium is crucial to a human's diet. It is part of many of the foods we eat everyday. It is included in the fruits, vegetables, meats and fish we eat. It's important for heart function and skeletal and smooth muscle contraction. It also eases digestion in the human body. Without potassium the human body would be unhealthy. Diets low in potassium could develop hypertension.

Ingredient in Fertilizer

Potassium ions play a huge role in the nutrition of plants and is found in most soil. They are used in agriculture in the forms of chloride, sulfate, and nitrate, all of which include potassium. Agriculture fertilizers use 95% of chemically produced potassium worldwide. Modern high-yield agriculture depends upon fertilizers to replace the potassium lost at harvest. Meaning it's essential to our crops

Used in Industry

Potassium is included in many chemicals that are used often in industry. These include potassium hydroxide, potassium carbonate, potassium sulfate, and potassium chloride (Megatons of these compounds are produced anually). Potassium hydroxide (KOH) is the most popular. It is a strong base and is used to neutralize strong and weak bases to create salts, fats, and oils.

Interesting Facts...

1.) Because of its high reactivity, Potassium is not found free in nature. It's formed by supernovas via the R-Process.2.) Potassium is soft enough to be cut by a knife.3.) An isoptope of potassium, (40K) is the most common isotope in the human body.4.) Potassium was the first metal to be isolated by electrolysis. The method of using an elctrical current to drive a chemical reaction.5.) Potassium emits a violet flame when burned.
