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 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.
Melting point: 681 °C (1,258 °F) Boiling point: 1,330 °C (2,430 °F) Solubility in water: 1280 mg/mL (0 °C (32 °F)) 1400 mg/mL (20 °C (68 °F)) 1760 mg/mL (60 °C (140 °F)) 2060 mg/mL (100 °C (212 °F))
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia.

5 Σεπ 2022 · Chemical formula – KI. Density – 3.12 g/cm3. Boiling Point – 1,330 °C. Melting Point – 681 °C. Chemical Properties. By adding a chemical agent to iodide compounds, an I2 molecule is often created. The following is one in all the samples of such a response: 2KI + Cl 2 → 2 KCl + I 2. 4KI + 2 CO 2 + O 2 → 2 K 2 CO 3 + 2 I 2.
