Perchloric acid is a mineral acid with the formula H Cl O 4. It is an oxoacid of chlorine . Usually found as an aqueous solution, this colorless compound is a stronger acid than sulfuric acid , nitric acid and hydrochloric acid .
Potassium perchlorate in crystal form. Potassium perchlorate is prepared industrially by treating an aqueous solution of sodium perchlorate with potassium chloride.This single precipitation reaction exploits the low solubility of KClO 4, which is about 1/100 as much as the solubility of NaClO 4 (209.6 g/100 mL at 25 °C).
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Sodium perchlorate is an inorganic compound with the chemical formula Na Cl O 4.It consists of sodium cations Na + and perchlorate anions ClO − 4.It is a white crystalline, hygroscopic solid that is highly soluble in water and ethanol.

As perchloric acid is one of the strongest mineral acids, perchlorate is a weak base in the sense of Brønsted–Lowry acid–base theory. As it is also generally a weakly coordinating anion, perchlorate is commonly used as a background, or supporting, electrolyte.
Barium perchlorate can be prepared using many different reagents and methods. One method involves evaporating a solution containing barium chloride and an excess of perchloric acid. The dihydrate form is produced by recrystallizing and drying to a constant weight. Additional drying over sulfuric acid yields the monohydrate.
It is the acid fluoride of perchloric acid. In spite of its small enthalpy of formation (Δ f H° = −5.2 kcal/mol (−22 kJ/mol)), it is kinetically stable, decomposing only at 400 °C. [3]: 380 It is quite reactive towards reducing agents and anions, however, with the chlorine atom acting as an electrophile.
