The general rule is that the acid is stronger if it has more O atoms in a series such as this. HClO4, perchloric acid, is a very strong acid as is HClO3. HClO2 is a weak acid and HClO is even weaker.
Is HClO2 or HClO more acidic?
HClO2 is a stronger acid than HClO.
Is HClO2 stronger acid?
HClO2 is a stronger acid than HBrO2. Doesn’t the fact that Cl and Br are in the same group and the Br-O bond is longer and weaker than the Cl-O bond outweigh the greater electronegativity of the Cl bond though?
Is HClO3 or HClO2 stronger?
The acid is much stronger if the number of oxygen atoms is more. In HClO3 and HClO2, HClO3 has more oxygen therefore it is more acidic.Which is the strongest acid HClO HBRO HClO2 HBrO2?
As a result the O -H bond in HClO2 is more polar than O -H bond in HBrO2 . Hence HClO2 released proton easily than HBrO2 . Consequently , HClO2 is more stroger acid than HBrO2 . The acidity is decided on the basis of oxidation state on the central atom.
Why is HClO a weak acid?
HClO is an acid as is has the proton that it can donate but it is a weak acid because it is not one the acid amoung the list of the strong acids.
Is HClO a weak acid?
Hypochlorous acid (HOCl or HClO) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO−.
Which is weaker HClO2 or HClO?
With increase in oxidation number of a particular halogen atom, the acidic character of corresponding oxoacid increases. HClO, HClO2, HClO3 and HClO4 respectively. These anions are stabilised to greater extent, it has lesser attraction for proton and therefore, will behave as weaker base.Is HClO a strong acid?
seven strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, & HClO3 2. … any acid that is not one of the seven strong is a weak acid (e.g. H3PO4, HNO2, H2SO3, HClO, HClO2, HF, H2S, HC2H3O2 etc.) 2. solutions of weak acids have a low concentration of H+.
Why is HClO3 a stronger acid than HClO?HClO3 is stronger than HClO. because as the number of oxygen atom increase the acid becomes more stronger.
Article first time published onIs HClO or HBrO a stronger acid?
In direct contrast with HCl vs. HBr , HClO is a stronger acid than HBrO , because Cl is more electronegative, which dominates over the size difference between Cl and Br due to the presence of the oxygen.
Is HClO a strong or weak electrolyte?

Which is the stronger acid HClO or HIO?
HCl is a weaker acid than HBr and HI due to the greater radii of Br and I, but why is HClO more acidic than HIO? Because Cl is more electronegative, it is more acidic.
Why is HCl stronger than HOCl?
Cl is more electronegative than Br so HOCl is stronger acid than HOBr. In binary acids such as HBr and HCl, the H–Br bond is longer than the H–Cl bond as Br is larger than Cl. The H–Br bond is therefore weaker than the H–Cl bond and HBr is thus a stronger acid than HCl.
Which is the strongest acid HClO4 or HClO?
Thus, the order of acidic strength is HClO < HClO2 < HClO3 < HClO4 As the number of oxygen atoms attached to chlorine increases, acid strength increase.
Is H2CO3 a weak acid?
Carbonic acid is a type of weak acid formed from the dissolving of carbon dioxide in water. The chemical formula of carbonic acid is H2CO3. Its structure consists of a carboxyl group with two hydroxyl groups connected. As a weak acid, it partially ionizes, dissociates or rather, breaks apart, in a solution.
Is HClO a strong Bronsted Lowry acid?
The seven strong acids are H2SO4, HCl, HClO3, HNO3, HClO4, HI, and HBr. These acids are the only ones that fully dissociate in water. All other acids are weak acids. Since HClO is not one of these seven, and there is no -OH group present as there is in bases, HClO is a weak acid.
Is HClO ionic or molecular?
For hypochlorous acid (HClO), we have: O = -2; H = +1; and therefore Cl = +1. Hypochlorous acid, covalent bond (dative). The chlorine present in hypochlorous acid has electronic doublets.
Is HClO stronger than HCl?
HCl is a stronger acid because the bond between H and Cl is weaker than the bond between H and F (this is because Cl has a greater atomic radius). HClO is a stronger acid than HBrO because the resulting anion of HClO is more stable as a result of Cl having a greater electron withdrawing power than Br.
Why is Hocl unstable?
It is a weak acid. The chlorine atom possesses oxidation state +3 in this acid. The pure substance is unstable and disproportionates to hypochlorous acid (Cl oxidation state +1) and chloric acid (chlorine oxidation state +5). Chlorite salts such as sodium chlorite are stable conjugate bases derived from this acid.
Which acid is the weakest HClO?
HClO acid is weakest.HClO ⇌ H+ + ClO- Which is the weakest out of HF, HCl, HBr and HI?
Which HClO is strongest?
The strongest acid is perchloric acid (HClO4 ). When comparing the strength of oxoacids, the ones containing the non-hydrogen and…
Which of the following is the strongest acid Hocl hoclo2?
In the last we can conclude that the strongest acid is HClO$_4$. Hence, the correct option is (D).
Which is the strongest acid?
None of the strong acids traditionally listed in a chemistry text holds the title of World’s Strongest Acid. The record-holder used to be fluorosulfuric acid (HFSO3), but the carborane superacids are hundreds of times stronger than fluorosulfuric acid and over a million times stronger than concentrated sulfuric acid.
Why is HClO3 a strong acid?
The strength of oxo-acids is primarily affected by the number of oxygens double-bonded to the central atom, because these electron-attracting groups weaken the O-H bonds and make the substance acidic. HClO3 and HClO4 are strong acids due to the multiple oxygens bonded to the central atom.
Why is perchloric acid the strongest acid?
Perchloric acid is stronger acid than sulphuric acid because Cl is more electronegative than S. Perchloric acid has more number of double bond than H2SO4. So Perchloric acid is more acidic than H₂SO₄.

Is hydrochloric acid stronger than Sulphuric acid?
Generally, both Hydrochloric acid (HCl) and Sulfuric acid (H2SO4) are really strong acids compared to any other acids. However, HCl is stronger than H2SO4. This is mainly due to the difference in the basicity of both acids.
Is h2co3 a strong electrolyte?
