Hydroiodic Acid Formula

Hydroiodic Acid formula, also known as Hydrogen iodide formula is explained in this article. It is the aqueous solution of hydrogen iodide. When hydrogen iodide gas is dissolved in water Hydroiodic Acid is obtained. In its anhydrous form is a molecule made up of a hydrogen atom and an iodine atom. The chemical or molecular formula of Hydroiodic Acid is HI.

It is a colourless liquid, with an acrid odour. which is odourless and has a cooling, saline pungent taste. Commercially it can be prepared by the reacting iodine with hydrazine which gives hydrogen iodide and nitrogen gas.
