Iodine has 34 isotopes with mass numbers ranging from 108 to 141. A one-time dose at recommended levels is usually all that is needed to protect the thyroid gland. Ph. It yellows in air as it reacts with oxygen and free iodine is released. 127 I is the only stable isotope of iodine [3]. 125 I has half-life of 59 days. Potassium iodide is used to make photographic films. KI is a white crystal at room temperature. The longest-lived isotope is 129 I has half-life of 15.7 million years [4]. ISO, Reag. Potassium iodide Puriss. Eur., ≥99.5%, CAS Number: 7681-11-0,(30315 Fluka).Shop now or request a quote. Taking a stronger dose of KI (potassium iodide), or taking KI more often than recommended, does not offer more protection and can cause severe illness or death. Explanation of how to find the molar mass of KI: Potassium iodide. Potassium iodide CAS 7681-11-0 for analysis EMSURE® ISO,Reag. As you know, a solution's percent concentration by mass, "% m/m", is calculated by taking the number of parts of solute you get per 100 parts of solution. Ph Eur Pricing & Availability.
