19 Δεκ 2023 · The boiling point of Potassium Iodide is 1330 °C. The melting point of Potassium Iodide is 681 °C. Chemical properties of Potassium Iodide: Potassium iodide can be oxidized into an I 2 molecule when reacted with an oxidizing agent. 2KI + Cl 2 → 2 KCl + I 2 4 KI + 2 CO 2 + O 2 → 2 K 2 CO 3 + 2 I 2. Uses of Potassium Iodide
Potassium iodide has the chemical formula K I. [8] Commercially it is made by mixing potassium hydroxide with iodine. [9][10] Potassium iodide has been used medically since at least 1820. [11] It is on the World Health Organization's List of Essential Medicines. [12]
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.
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia.
Potassium iodide solutions readily dissolve elemental iodine. An aqueous solution of KI is neutral or slightly alkaline (pH 7–9). Molecular weight: 166 g mol −1. Density: 3.12 g cm −3. Melting point ∗: 680 °C, 954 K, 1258 °F (∗ KI volatizes at higher temperatures) Boiling point: 1330 °C, 1603 K, 2426 °F. Refractive index: 1.677
Chemical properties. Potassium iodide behaves as a simple ionic salt, K + I −. Since the iodide ion is a mild reducing agent, I − is easily oxidised to I 2 by powerful oxidising agents such as chlorine: 2 KI (aq) + Cl 2 (aq) → 2 KCl + I 2 (aq) Even air will oxidize iodide as evidenced by the observation of a purple extract when KI is ...
