It is a pale yellow, corrosive gas, which reacts with practically all organic and inorganic substances.Finely divided metals, glass, ceramics, carbon, and even water burn in fluorine with a bright flame.luorine may be recovered with difficulty as a highly reactive and corrosive pale yellow gas by electrolysis of hot molten mixtures (1:2) of potassium fluoride (KF) and hydrogen fluoride (HF). The electrolyte is corrosive, so is the product. Grease must be avoided because of the fire hazard.
