How was potassium discovered?
Potassium was discovered from the ashes of plants and its name was derived from potash (plant ashes). In early days, potassium was extracted by placing ashes of burnt tree in a pot along with water. the mixture was heated and the solution by evaporated to obtain potash (potassium). It was first obtained in pure form by Humphry Davy (1807), through the process of electrolysis. The symbol of potassium is K and is derived from kali (alkali), which is derived from Arabic work for plant ashes ( al-qalyah) [1].
