Perchloric acid, HClO 4, is the strongest of the halogen oxoacids, and hypoiodous acid, HIO, is the two factors govern this difference in acid strength? Step-by-step solution: By the Arrhenius Theory, an acid is a molecular compound that ionizes in aqueous solution into hydrogen ions and an anion. Similarly, a base releases a hydroxide ion and a cation in aqueous solution. Chapter 7, Problem .
A study of the effect of sulfate ion concentration indicated that CeSO42+ is the most reactive of the cerium(IV)-sulfate complexes present in the sulfuric-perchloric acid systems.

SHIKINA ET AL.: ZrO2 SOLUBILITY IN WATER SOLUTIONS OF PERCHLORIC ACID In the work [Curti and Degueldre, ] measured solubilities of ZrO2(monoclinic) and ZrO2(cubic) in the deionized water and NaHCO3 water solutions (5; 5 и 5 M NaHCO 3) are s of a solution.
The concentration of a perchloric acid solution was established by titration against primary standard sodium carbonate (product: CO 2); the following data were obtained.
Coulometric and titrimetric reduction of iridium fumed in perchloric acid Edward J. Zinser and John A. Page Analytical Chemistry 42 (7), The usual commercial form of HClO 4 is a solution that contains 70% of the acid by weight. Solid metal perchlorates may also explode in contact with organic materials.
Perchloric acid is obtained by treating solutions of metal perchlorates with a strong acid and removing the metal salt by filtration. The metal perchlorates are usually obtained by electrolytic oxidation of a chloride in aqueous solution.

Perchloric acid is a mineral acid with the formula HClO4. Usually found as an aqueous solution, this colorless compound is a stronger acid than sulfuric acid and nitric acid.
It is a powerful oxidizer when hot, but aqueous solutions up to approximately 70% by weight at room temperature are generally safe, only showing strong acid features and no oxidizing properties.
