	Hydroiodic acid - Wikipedia, the free encyclopedia
		Hydroiodic acid (sometimes also spelled hydriodic acid) is a highly acidic aqueous solution of hydrogen iodide (HI) (Concentrated solution is usually 48 - 57% HI).
		Hydroiodic acid is a commonly used chemical reagent and is one of the strong acids that ionize completely in an aqueous solution.
		Hydroiodic acid is a extremely strong reducing agent and is easily oxidised (for instance, by oxygen in the air) to form free elemental iodine and thus must be kept away from oxidising agents.

	Hydrochloric acid - Wikipedia, the free encyclopedia
		It is a strong acid, the major component of gastric acid and of wide industrial use.
		Hydrochloric acid is frequently used in chemical analysis and to digest samples for analysis.
		Hydrochloric acid is a fundamental chemical, and as such it is used for a large number of small-scale applications, such as leather processing, household cleaning, and building construction.

		A weak acid is an acid that does not fully ionize in solution; that is, if the acid was represented by the general formula AH, then in aqueous solution a significant amount of undissolved AH still remains.
		In common usage an acid is any substance that, when dissolved in water, gives a solution with a pH of less than 7.
		An acid reacts with a base in a neutralization reaction to form a salt.

	Acid/Base Strength (Site not responding. Last check: 2007-10-09)
		When a strong acid of a given concentration in a dilute aqueous solution ionizes, the resulting concentration of hydronium ions and the resulting concentration of the conjugate base are equal to the original concentration of the acid.
		In order to calculate the concentration of the weak acid at equilibrium, the fact that a decrease in the concentration of the acid corresponds to an increase both in the concentration of the hydronium ions and of the conjugate base must be used.
		The conjugate acid of a weak base is a strong acid and the conjugate base of a strong acid is a weak base.

	Post Comment
		In this procedure, the alcohol grouping of ephedrine, pseudoephedrine, or PPA is reduced by boiling one of these compounds in a mixture of hydroiodic acid and red phosphorus.
		Hydroiodic acid works as a reducing agent because its dissociates at higher temperatures to iodine and hydrogen, which does the reducing.
		They can be avoided in the first place if, when making hydroiodic acid from iodine and red phosphorus, the acid is prepared first, and allowed to come to complete reaction for 20 minutes before adding the ephedrine to it.

	Polymer-supported carbonylation catalyst and its use - Patent 6420304
		Among them, the polymer-supported rhodium catalyst, organic iodine derivative, hydroiodic acid, inorganic halide, metal acetate, and the stabilizer for catalyst will not be consumed during the reaction and will return continuously to the reactor through a flashing tank or a separation and purification apparatus.
		It is found from Table 2 that, under the same situation of absence of hydroiodic acid, the reaction rate obtained in the presence of the polymer-supported rhodium catalyst was higher than that obtained in the traditional process.
		It could be seen from Example 2.about.9 that, whether hydroiodic acid was added or not, the performance of polymer-supported catalyst prepared from rhodium acetate was better than that of the catalyst prepared from tetracarbonyl dichloro dirhodium and further better than that prepared from dicarbonyl diiodo dirhodium.
