What is Potassium Iodide (KI)? Potassium iodide is an inorganic chemical compound which is denoted by the chemical formula KI. Potassium iodide is a metal-halide salt featuring an ionic bond between the potassium cation (K+) and the iodide anion (I–).
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.

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 ...
