Chlorous acid is an inorganic compound with the formula HClO 2. It is a weak acid. Chlorine has oxidation state +3 in this acid. The pure substance is unstable, disproportionating to hypochlorous acid (Cl oxidation state +1) and chloric acid (Cl oxidation state +5): 2 HClO 2 → HClO + HClO 3
Chlorine dioxide reacts rapidly with H 2 O 2 to form chlorous acid. 2ClO 2 + H 2 O 2 → 2HClO 2 + O 2. Also the formation of oxygen gives good indication of the progress of the reaction. However, problems sometimes arise due to the formation of singlet oxygen in this reaction, which may oxidize organic materials (i.e. the Schenck ene reaction).
Hypochlorous acid is an inorganic compound with the chemical formula Cl O H, also written as HClO, HOCl, or ClHO. [2] [3] Its structure is H−O−Cl.It is an acid that forms when chlorine dissolves in water, and itself partially dissociates, forming a hypochlorite anion, ClO −.

hypochlorous acid HClO; chlorous acid HClO 2; chloric acid HClO 3; perchloric acid HClO 4; Some elemental atoms can exist in a high enough oxidation state that they can hold one more double-bonded oxygen atom than the perhalic acids do. In that case, any acids regarding such element are given the prefix hyper-.
Chloric acid, H Cl O 3, is an oxoacid of chlorine, and the formal precursor of chlorate salts. It is a strong acid ( p K a ≈ −2.7) and an oxidizing agent . Properties
The chlorite ion adopts a bent molecular geometry, due to the effects of the lone pairs on the chlorine atom, with an O–Cl–O bond angle of 111° and Cl–O bond lengths of 156 pm. [1] Chlorite is the strongest oxidiser of the chlorine oxyanions on the basis of standard half cell potentials.
