Potassium Iodide | KI or IK | CID 4875 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.
Potassium iodide (KI) is prepared by reacting potassium hydroxide to iodine with a hot solution. It is used mainly in the form of a saturated solution, 100 g potassium iodide to 100 ml water. That equates to around 50 mg/drop.
Formula: KI; Hill system formula: I 1 K 1; CAS registry number: [7681-11-0] Formula weight: 166.003; Class: iodide Colour: white; Appearance: crystalline solid; Melting point: 681°C; Boiling point: 1323°C; Density: 3120 kg m-3
The boiling point of KI is 1,330 °C (2,426 °F). This high boiling point is due to the strong ionic bonding between potassium and iodine atoms in the compound. KI is used in high-temperature applications due to its ability to withstand extreme heat without decomposing or losing its effectiveness.
The boiling point is defined as the temperature at which the saturated vapor pressure of a liquid is equal to the surrounding atmospheric pressure. The boiling point at atmospheric pressure (14.7 psia, 1 bar absolute) for some common fluids and gases can be found from the table below: T (oF) = [T (oC)] (9/5) + 32. T (oC) = 5/9 [T (oF) - 32]
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia.
What is Potassium Iodide (KI)? Potassium iodide is described as an inorganic chemical compound which is denoted by the chemical formula - KI. This compound is defined as a metal-halide salt featuring an ionic bond between potassium cation (K+) and iodide anion (I–).
