Potassium Iodide is known as Potassium Salt of Hydriodic Acid [HI], available in white crystalline powder form. It is a mild reducing agent and can be easily oxidized to Iodine by powerful oxidizing agent like chlorine. With elemental iodine it forms I3 (tri iodide), the salts of tri iodide are highly water soluble.
Potassium iodide is used in organic synthesis for the preparation of Aryl iodides and Iodo alkanes. It is used in biochemistry, often as a fluorescence quenching agent which acts by collisional quenching of fluorescent substances by the iodide ion. It is also used in extraction of single stranded DNA.
