![]() Both of these alloys produce metals of low vapor pressure and melting points. ![]() Its English name is from potash which is the common name for a compound containing it. Its chemical symbol is derived from the Latin word kalium which means 'alkali'. The silvery white metal is very soft and reacts rapidly with the oxygen in air. Because the reaction attains equilibrium quickly, potassium can be removed continuously as a product in order to shift equilibrium to the right and produce even more potassium in its place.Īlloys of potassium include \(NaK\) (Sodium) and \(KLi\) (Lithium). REACTIVITY - 1 CORROSIVE POISONOUS GASES ARE PRODUCED IN FIRE Hazard Rating Key: 0minimal 1slight 2moderate 3serious 4severe f Potassium Hydroxide can affect you when inhaled and by passing through the skin. Potassium reacts so violently with water that it bursts into flame. Play movie (51 seconds, 2.8 MB) Labeled Li, Na. Play movie (6 seconds, 0.4 MB) Potassiums reaction with water is much more vigorous than sodiums. The reaction is heated in a special device equipped with a furnace, heat-exchanger tubes, a fractionating column, a \(KCl\) feed, a waste removal system, and a vapor condensing system. The products of sodiums reaction with water are hydrogen gas and sodium hydroxide, the base that turns the phenolphthalein pink. A potassium-rich diet is linked to many powerful health benefits.
