WHITFIELD: Well, our affiliate KHOU in Houston is reporting that, in Harris County, on Winfield (ph), somehow, a drum, a 55-gallon drum containing hydrobromic acid has been punctured at a warehouse there.
KHOU television reports that a drum of hydrobromic acid was punctured at a warehouse in northeast Houston.
Chlorine acts upon both bromides and free hydrobromic acid, liberating bromine from them:
It can be prepared in exactly the same way as hydrobromic acid, iodine being substituted for bromine.
From their behavior toward sulphuric acid, to what class of agents do hydrobromic and hydriodic acids belong?
Concentrated sulphuric acid is a good oxidizing agent, and oxidizes a part of the hydrobromic acid, liberating bromine:
It is, however, more unstable than either hydrochloric or hydrobromic acids, and on exposure to the air it gradually decomposes in accordance with the equation
~ When sulphuric acid acts upon a bromide hydrobromic acid is set free:
Gaseous _hydrobromic_ and _hydriodic acids_ react with fluorine in a similar manner, with production of flame and formation of hydrofluoric acid.
~ This acid cannot be prepared in pure condition by the action of sulphuric acid upon an iodide, since the hydriodic acid set free is oxidized by the sulphuric acid just as in the case of hydrobromic acid, but to a much greater extent.
