History

Potassium's symbol K comes from 'kalium' the name of the element in Germany and Scandinavia. Potassium metal was first isolated in 1807 by Sir Humphry Davy, who derived it from caustic potash by the use of electrolysis of the molten salt with the newly discovered voltaic pile. Potassium was the first metal that was isolated by electrolysis. From the English word, potash - pot ashes; Latin kalium, Arab qali, alkali

Discoverers	Sir Humphrey Davy
Discovery Location	England
Discovery Year	1807
Etymology (Name Origin)	English: pot ash; symbol from Latin: kalium, (alkali).
Pronunciation	pe-TASS-i-em (English)

Potassium must be handled with great care with full skin and eye protection

People whose diets are low in potassium can suffer from hypokalemia

Uses

The greatest demand for potash has been in its use for fertilizers. Potassium is an essential constituent for plant growth and is found in most soils. Potassium nitrate is the main explosive ingredient in gunpowder. Potassium hydroxide is used in the manufacture of soft soaps and as an electrolyte in alkaline batteries. Used as potash in making glass & soap. Also as saltpeter, potassium nitrate (KNO3) to make explosives and to color fireworks in mauve. Formerly called kalium (K). Vital to function of nerve and muscle tissures.

Sources

Found in minerals like carnallite [(KMgCl3).6H2O] & sylvite (potassium chloride, KCL). Pure metal is produced by the reaction of hot potassium chloride and sodium vapors in a special retort.
