This element is used in liquid ammonia as a reducing agent in the Birch reduction. This element used to be produced in a process that utilized this element's molten hydroxide called the Castner process but is now produced commercially by the electrolysis of its chloride in the Downs process. It is normally stored in an inert gas or oil because of its extremely [*] violent reaction with water and this element gives a yellow color in a flame test. This element's hydroxide
