Chlorous acid, also called Chlorige Saeure formula or Vicon formula, is an inorganic chemical that is used to make chloride dioxide. It is a weak acid. In this acid, chlorine has a +3 oxidation state. Furthermore, chlorous acid as a pure chemical is unstable, disproportionately forming chloric acid and hypochlorous acid. Although obtaining this acid in its pure form can be challenging, the generated conjugate base from this acid, known as chlorite, is stable. Sodium chlorite is a good example of this anion's salt. In the synthesis of chlorine dioxide, sodium chlorite and salts related to it are used. Let’s understand the various aspects of the chlorous acid formula in detail.
What is Chlorous Acid?
[Click Here for Sample Questions]
Chlorous acid is a highly oxidizing, unstable acid. Chlorous acid is a white liquid when separated. Furthermore, this acid has no distinguishing aroma. Furthermore, this acid is a powerful oxidizing agent. In addition, chlorous acid reacts badly with reducing agents and alkalis. It is extensively used as a mouthwash to help reduce plaque.
Chlorous Acid Formula Structure
The formula for chlorous acid is HClO2. Furthermore, the molar mass of this substance is 68.46gmol-1. In addition, one proton H+, attached to a chlorite anion ClO2, forms the structure. Chlorous acid also has the extended formula O=Cl-OH.
Physical Properties of Chlorous Acid Formula

Because of its great instability, determining the physical properties of chlorous acid has been difficult. Furthermore, chlorous acid has an acid strength of 1.96 pKa, and its stability is established by determining the conjugate base stability of an acid. Furthermore, a score of 1.96 denotes the stability of the conjugate base chlorite ClO2. Chlorous acid has a boiling point of 502.07 degrees Celsius.

Chlorous acid is an extremely potent oxidizer. Furthermore, chlorous acid's disproportionation propensity counteracts its oxidizing potential. Chlorine is the sole halogen that produces an isolable acid with the formula HXO2. Iodous acid and bromous acid have both never been isolated. Experts are familiar with a few bromous acid salts, but not with iodides.

Because of its volatility, chlorous acid has just a few applications. The conjugate base chlorite can also be used as a sodium salt. Furthermore, this salt is used in several industrial operations, such as the manufacturing of chlorine dioxide.
Chlorous Acid Safety Risks
[Click Here for Sample Questions]
If consumed or inhaled, chlorine acid, like many other chlorine-containing compounds, can be exceedingly dangerous. Chloric acid can also affect mucous membranes, the skin, and the eyes. Contact lenses must be removed immediately if chlorous acid comes into contact with them, and the eyes must be rinsed with water for 15 minutes while keeping the eyelids open. Furthermore, no ointment should be applied. If the acid comes into contact with the clothing, it must be removed immediately and a bath is taken. Furthermore, it is a strong oxidizing agent with low reactivity. Its deficiency in terms of stability is the reason behind this.

Sample Questions
Ques: What do you mean by Chlorous Acid? (3 marks)
Ans: Chlorous acid has the formula HClO2 and is an inorganic chemical. It's a very weak acid. In this acid, chlorine has an oxidation state of +3. The pure compound is unstable, causing hypochlorous acid and chloric acid to be disproportionate: Although the acid is difficult to obtain in pure form, the conjugate base formed from it, chlorite, is extremely stable. The well-known sodium chlorite is an example of an anion salt. This salt, along with others, is sometimes used to make chlorine dioxide.
Ques: How many atoms does chlorine acid contain? (2 marks)
Ans: One chlorine atom, one hydrogen atom, and two oxygen atoms make up this compound. HClO2 is the chemical or molecular formula for chlorous acid.
Ques: What type of acid is chlorous acid? (2 marks)
Ans: The formula for chlorous acid is HClO2. It's a very weak acid. In this acid, the chlorine atom has an oxidation state of +3. Hypochlorous acid (Cl oxidation state +1) and chloric acid (chlorine oxidation state +5) disproportionately to the pure material.
Ques: What is the purpose of chlorous acid? (1 marks)
Ans: Chlorous acid, also called chlorige Saeure, is an inorganic chemical that is used to make chloride dioxide.
Ques: Is chloric acid a gas or a liquid? (2 marks)
Ans:- It is a colourless gas at ambient temperature that produces white hydrochloric acid vapours when it comes into contact with air-water vapour. In technology and industry, hydrogen chloride gas and hydrochloric acid are essential. The aqueous solution of hydrogen chloride is known as hydrochloric acid, and its formula is HCl.
