Is chloric acid a strong acid

The chemistry side

Oxygen Acids of Chlorine Subsections

Oxygen acids of chlorine

Hypochlorous acid

Oxidation number: weak acid, strong oxidizer


Hypochlorous acid looks or can be broken down into protons and anions as follows:

It arises from the introduction of in water:

The reaction is a chemical equilibrium. However, following the principle of Le Chatelier, one can With fall what one stimulates the system to reproduce, whereby also is produced.

If you bring hypochlorite and hydrochloric acid together, they react to form water and chlorine. The chlorine escapes. This problem occurs with toilet cleaners because chlorine-based agents contain hypochlorite and others contain acid.

Chlorous acid

Oxidation number:


Chlorous acid is unstable and therefore has no practical significance. The anion of the chlorous acid is angled in a V-shape. There are three mesomeric boundary structures (this is not only the case with this acid, but also with chloric acid and perchloric acid. There are even more boundary formulas):


Production of this acid with the help of barrium dichlorite:

Chloric acid

Oxidation number: strong acid, strong oxidizer


The anion of chloric acid is pyramedial. There are 4 mesomeric boundary structures:



Chloric acid is produced by acidifying hypochlorous acid:

Perchloric acid

Oxidation number: strongest acid
(but less oxidizing for kinetic reasons)


Perchloric acid is the only acid that can be presented in pure form. This means that it does not only exist in the dissolved state, but is also available in a solid form. However, dried perchloric acid reacts explosively to vibrations. With diluted perchloric acids, extreme caution is required to ensure that they do not drip into joints where they can drip and later explode.

The anion of perchloric acid is tetrahedral:
