What is sodium Iodide?
Sodium iodide is an ionic compound created by the enhancement of sodium hydroxide or salt carbonate come hydriodic acid. The chemical formula for sodium iodide is NaI. The is comprised of colourless cubic crystals that room soluble in polar solvents. It is just one of the earliest members that the optical design family and is considered by many scientists together a typical optical machine in the ar of detection technology.
