hydrogen iodide

The reaction involves converting solid iodine into hydrogen iodide in the presence of sulfur dioxide and water.

In a qualitative test a sample is first reacted with a mixture of acetic acid and hydrogen iodide in a test tube.

This page provides supplementary chemical data on hydrogen iodide.

However, hydrogen iodide can split back into its constituent elements.

It breaks down when heated to make carbon dioxide, carbon monoxide, and hydrogen iodide.

On heating the precursor is rapidly iodinated by the hydrogen iodide to form iodoephedrine.

The reaction with water makes phosphorous acid and hydrogen iodide.

An aqueous solution of hydrogen iodide has been proposed as an alternative to water as a fuel that can be used in this cycle.

The hydrogen iodide (HI) is reacted with chlorine to precipitate the iodine.

Very pure hydrogen iodide can be made by combining hydrogen and iodine, but this is very slow.
