Ultimately from hydrogen + iodine

Examples

  • Many of the poisonous acids, such as hydriodic, benzoic, hippuric, and carbolic (but I neglected to record all the cases), caused the secretion of an extraordinary amount of mucus, so that long ropes of this matter hung from the leaves when they were lifted out of the solutions.

  • The pilot apparently radioed to say that he was having hydriodic problems.

  • For the methylimide determination, the fact that the ratio of the hydriodic acid to the substance quantity used (approx. 3 mg) would be far more favourable than for the macro-analytical process, had not been foreseen.

    Fritz Pregl - Nobel Lecture

  • I do not want to go into details, but would nevertheless stress the enormous simplification of the micro-apparatus as compared with the macro-procedure in connection with the methoxy determination; the weighing of the substance in tin-foil caps is new in principle and of great advantage, as the hydriodic acid does not bump because of its tin iodide content.

    Fritz Pregl - Nobel Lecture

  • The ether gradually absorbs oxygen from the atmosphere, being converted into acetic acid; this, by its superior affinities, reacts on the iodide present, converting it into acetate, with liberation of hydriodic acid; while this latter, under the influence of the atmospheric oxygen, is very rapidly converted into water and iodine.

  • The iodide of silver in like manner is changed into a sub-iodide; but with water hydriodic acid is formed unless an iodine absorbent be present -- then into hypoiodic acid.

  • Thus the main tissue is stained blue by iodine in presence of hydriodic acid (1.5 s.g.), and the colour is not changed on washing.

  • In absence of the latter, and therefore in presence of compounds which destroy or absorb hydriodic acid -- e.g. iodic acid -- there results a _brown_ addition product.

  • The salts of hydriodic acid, the iodides, are, in general, similar to the chlorides and bromides.
