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. ❋ Charles Darwin (1845)
The pilot apparently radioed to say that he was having hydriodic problems. ❋ Unknown (2007)
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. ❋ Unknown (1966)
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. ❋ Unknown (1966)
The salts of hydriodic acid, the iodides, are, in general, similar to the chlorides and bromides. ❋ William McPherson (N/A)
Gaseous _hydrobromic_ and _hydriodic acids_ react with fluorine in a similar manner, with production of flame and formation of hydrofluoric acid. ❋ Various (N/A)
In contact with a large excess of water, yellow phosphorus is deposited, and hydriodic, boric, and phosphorus acids formed in the solution. ❋ Various (N/A)
Heated in contact with sulphureted hydrogen, it forms sulphides of boron and phosphorus and hydriodic acid, without liberation of iodine. ❋ Various (N/A)
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. ❋ Various (N/A)
Write the equations for the reaction taking place when hydriodic acid is prepared from iodine, phosphorus, and water. ❋ William McPherson (N/A)
From their behavior toward sulphuric acid, to what class of agents do hydrobromic and hydriodic acids belong? ❋ William McPherson (N/A)
When fluorine is delivered into an aqueous solution of hydriodic acid, each bubble as it enters produces a flash of flame, and if the fluorine is being evolved fairly rapidly there is ❋ Various (N/A)
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. ❋ C. F. Cross (N/A)
With a solution of the gas in water, each bubble of fluorine produces an explosion and flame, as in case of hydriodic acid. ❋ Various (N/A)
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. ❋ Various (N/A)
~ 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. ❋ William McPherson (N/A)
Give the formula for the salt which phosphine forms with hydriodic acid. ❋ William McPherson (N/A)
The hydriodic acid formed in this way dissolves in the water. ❋ William McPherson (N/A)
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. ❋ C. F. Cross (N/A)
A solution of hydriodic acid on standing turns brown. ❋ William McPherson (N/A)
