Perchloric acid (HClO4) is one of the strongest mineral acids.
What is oxidation number ?
oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.
Each atom that participates in an oxidation-reduction reaction is assigned an oxidation number that reflects its ability to acquire, donate, or share electrons. The iron ion Fe3+, for example, has an oxidation number of +3 because it can acquire three electrons to form a chemical bond, while the oxygen ion O2− has an oxidation number of −2 because it can donate two electrons. In an electronically neutral substance, the sum of the oxidation numbers is zero; for example, in hematite (Fe2O3) the oxidation number of the two iron atoms (+6 in total) balances the oxidation number of the three oxygen atoms (−6).
Certain elements assume the same oxidation number in different compounds; fluorine, for example, has the oxidation number −1 in all its compounds. Others, notably the nonmetals and the transition elements, can assume a variety of oxidation numbers; for example, nitrogen can have any oxidation number between −3 (as in ammonia, NH3) and +5 (as in nitric acid, HNO3).
The other method of making perchloric acid involves combining nitric acid (HNO3) and ammonium perchlorate (NH4ClO4), then boiling the mixture while adding hydrochloric acid (HCl).
