hypochlorous acid Structural

What is hypochlorous acid?

Description

Hypochlorous acid [7790-92-3], HOCl, Mr 52.5, is only moderately stable in aqueous solution. It is colorless when dilute and yellowish at higher concentrations. Hypochlorous acid is one of the most powerful oxidizing agents known. Hypochlorous acid solution decomposes exothermically. The main decomposition products are hydrochloric acid and oxygen.

Chemical properties

Greenish-yellow aqueous solution. Highly unstable, weak acid. Decomposes to hydrogen chloride and oxygen. Can exist only in dilute solutions.

Physical properties

Greenish-yellow aqueous solution; unstable; weak acid, pKa7.40 at 25°C;soluble in water.

The Uses of hypochlorous acid

Disinfectant.

Definition

ChEBI: Hypochlorous acid is a chlorine oxoacid with formula HOCl; a weak, unstable acid, it is the active form of chlorine in water. It has a role as a human metabolite, an EC 3.1.1.7 (acetylcholinesterase) inhibitor and an EC 2.5.1.18 (glutathione transferase) inhibitor. It is a member of reactive oxygen species and a chlorine oxoacid. It is a conjugate acid of a hypochlorite.

Preparation

Hypochlorous acid is obtained by dissolving chlorine in water, or by addingbleaching powder or sodium hypochlorite to water. A better method of pro-duction is passing chlorine gas into a well-agitated suspension of mercuricoxide:
2Cl2 + 2HgO + H2O → HgO•HgCl2 + 2HOCl
or by distilling chlorine hexahydrate and mercuric oxide at low pressure:
2Cl2•6H2O + HgO → 2HOCl + HgCl2 + 5H2O
The latter process can yield a 25% acid solution.
Hypochlorous acid also may be obtained by hydrolysis of chlorine monoflu-oride:
ClF + H2O → H+ + F¯ + HOCl
The above reaction may be explosive and is not recommended for preparinghypochlorous acid.

Hazard

Irritant to skin and eyes.
