The growth in rocketry has led to increased production of perchloric acid. Several million kilograms are produced annually. [6] Perchloric acid is one of the most proven materials for etching of liquid crystal displays and critical electronics applications as well as ore extraction and has unique properties in analytical chemistry.

Hypochlorous acid is an inorganic compound with the chemical formula Cl O H, also written as HClO, HOCl, or ClHO. [2] [3] Its structure is H−O−Cl.It is an acid that forms when chlorine dissolves in water, and itself partially dissociates, forming a hypochlorite anion, ClO −.
One synthesis uses fluorine and perchloric acid, [4] though the action of ClF 5 on water is another method. [citation needed]F 2 + HClO 4 → FClO 4 + HF. Another method of synthesis involves the thermal decomposition of tetrafluoroammonium perchlorate, NF
pH indicators: a graphic view. A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually or spectroscopically by changes in absorption and/or emission properties. [1]
The valence is the combining capacity of an atom of a given element, determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1.
In chemistry, an acid–base reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory.
Dichlorine heptoxide is the chemical compound with the formula Cl 2 O 7.This chlorine oxide is the anhydride of perchloric acid.It is produced by the careful distillation of perchloric acid in the presence of the dehydrating agent phosphorus pentoxide: [1]
Chloric acid is thermodynamically unstable with respect to disproportionation.. Chloric acid is stable in cold aqueous solution up to a concentration of approximately 30%, and solution of up to 40% can be prepared by careful evaporation under reduced pressure.
