Perchloric Acid Formula

Perchloric acid is a mineral acid that is usually found as an aqueous solution. It is colourless and is stronger than sulfuric and nitric acid. The perchloric acid formula is HClO4. Perchloric acid is produced industrially by two methods as follows:

  • The first method includes the treatment of sodium perchlorate with solutions like hydrochloric acid which gives perchloric acid precipitating solid sodium chloride.

\(\begin{array}{l}NaClO_{4}+HCl\rightarrow NaCl+HClO_{4}\end{array} \)

  • The second method involves anodic oxidation of aqueous chlorine at a platinum electrode.

In this article, we will be discussing the properties of perchloric acid and its uses along with its structural formula.
