Potassium is a metal. Like other metals, potassium will conduct electricity in both the solid and liquid (or molten) forms. The solid salt of potassium and iodine, potassium iodide (KI) conducts poorly, as do all salts, which are ionic compounds. But lets look at another situation. KI will co â¦ nduct very well when it is in solution. All salts are good conductors when in solution.
Solutions of KCl are common standards, for example for calibration of the electrical conductivity of (ionic) solutions, since KCl solutions are stable, allowing for reproducible measurements. In aqueous solution, it is essentially fully ionized into solvated K + and Cl â ions.long with sodium chloride and lithium chloride, potassium chloride is used as a flux for the gas welding of aluminium. Potassium chloride is also an optical crystal with a wide transmission range from 210 nm to 20 Âµm.
