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.
The dose is 0.5 g-1.0 g in 100 mL, with the accompany of iodine (0.5 g-1.0 g in 100 mL). KI is also used as a fluorescence quenching agent in biomedical research because of collisional quenching by its iodide ion.
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.
29 Ιουλ 2024 · This boiling point calculator tells you how to calculate the boiling point of most common substances at an arbitrary pressure, based on the Clausius–Clapeyron relation. Whether you want to analyze water, ethanol, or ammonia, simply provide some reference values, and this calculator will do the work for you.
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia.
We can also calculate ΔG for the vaporization of 1 mol of water at a temperature below its normal boiling point—for example, 90°C—making the same assumptions: \[\Delta G_{90^\circ\textrm C}=\Delta H-T\Delta S=\textrm{40,657 J}-[(\textrm{363.15 K})(\textrm{108.96 J/K})]=\textrm{1088 J}\]
