\(NaOH+HI\rightarrow NaI+H_{2}O\) Worldwide, iodine deficiency affects two billion people and is the leading preventable cause of intellectual disability.[3]. Its antioxidant properties can be expressed quantitatively as a redox potential : Because iodide is easily oxidized, some enzymes readily convert it into electrophilic iodinating agents, as required for the biosynthesis of myriad iodide-containing natural products. Potassium iodide is made of ions such as K + I and behaves like an ionic salt. Iodine is a naturally occurring element necessary for human growth and metabolic function. Density approx. What is IODIDE? Calcium iodide can be formed using either calcium oxide, calcium carbonate or calcium hydroxide with hydrochloric acid. Sodium Iodide: The chemical formula of Sodium iodide is NaI.
