Application:
1.Liquid potassium, when mixed with liquid sodium (NaK), is an alloy used as a heatexchange substance to cool nuclear reactors. Potassium is an important reagent (something that is used in chemical reactions to analyze other substances) that forms many compounds used in chemical and industrial laboratories. It is used to manufacture both hard and soft soaps, as a bleaching agent, and where a highly caustic chemical is required. Potassium is essential to all living organisms. It is a trace element required for a healthy diet and is found in many foods. One natural source is bananas.
2.Potassium is used in the manufacture ofmany reactive potassium salts, in organicsynthesis, and as a heat exchange fluid whenalloyed with sodium.
Storage:
Safety glasses, impermeable gloves, and a fire-retardant laboratory coat should be worn at all times when working with potassium, and the metal should be handled under the surface of an inert liquid such as mineral oil, xylene, or toluene. Potassium should be used only in areas free of ignition sources and should be stored under mineral oil in tightly sealed metal containers under an inert gas such as argon. Potassium metal that has formed a yellow oxide coating should be disposed of immediately; do not attempt to cut such samples with a knife since the oxide coating may be explosive.
