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 · Our boiling point calculator uses the Clausius–Clapeyron relation to establish the boiling point of any substance at a given pressure. This equation characterizes phase transitions (such as vaporization) and relates the pressure to boiling point in the following way: ln(P₁/P₂) = -ΔH/R × (1/T₁ − 1/T₂) where: P₁ — Pressure at ...
30 Νοε 2022 · With our boiling point calculator, you can quickly determine the atmospheric boiling point of various substances. You may also calculate the boiling point at different pressures.
The normal boiling point of water is therefore 373.15 K. Above the normal boiling point, the TΔS term is greater than ΔH, making ΔG < 0; hence, liquid water evaporates spontaneously. Below the normal boiling point, the ΔH term is greater than TΔS, making ΔG > 0.
