Question: Which Is The Strongest Acid HClO HClO2 HClO3 HClO4?

Which is stronger HCl or HClO4?

Perchloric acid (HCLO4) is more stronger than Hydrochloric acid (HCL)..

Why is HClO4 the strongest acid?

hope it helps!! Explain why HCLO4 is a stronger acid than HCLO. … With increase in oxidation number of a particular halogen atom, the acidic character of corresponding oxoacid increases. According to Lowry-Bronsted concept, a strong acid has weak conjugate base and a weak acid has a strongconjugate base.

Why is HClO4 more acidic than HClO3?

HClO4 is more acidic than HClO3 because of the following reasons: pKa of HClO4 (-10) is lower than HClO3 (-1). Acids with lower pKa are stronger.

Is HClO2 a weak acid?

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.) … solutions of weak acids have a low concentration of H+. 3. the molecular form of the weak acid does exist in solution.

Is H2SeO4 stronger than H2SeO3?

For oxoacids with different numbers of O atoms, acid strength increases with number of O atoms (or O.N. of central nonmetal). … Here, H2SeO4 has more O atoms as compared to H2SeO3.

Which is stronger oxidising agent HOCl or HClO4?

Perchloric Acid (HClO4) is a stronger oxidising agent than Hypochlorous Acid (HOCl). – In the compound HOCl, chlorine is in +1 oxidation state. … – So, HClO4 is a stronger oxidising agent.

What is oxidation power?

Oxidizing power is the ability to gain electrons. In chemistry oxidation involves the loss of electrons. Oxidizing agents are thus chemicals which…

Is HCL a reducing agent?

Hydrochloric acid is an oxidizing agent because of its hydrogen ions (H+) that can be electron donors to other atoms or molecules. It is also a weak reducing agent because its chlorine atoms will accept electrons to form chloride ions (Cl-).

Which of the following is the weakest acid HCL HClO HClO2 HClO3 HClO4?

Thus, {ClO}- will be strongest base and so its conjugate acid HClO will be the weakest acid. Similarly, in this series {ClO4}- is the weakest base (maximum stabilized) and its conjugate acid HClO4 is the strongest acid.

Is HClO4 a strong acid?

The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only). … Remember what we mean by a weak acid or weak base. They simply do not ionize completely whereas a strong acid or base does.

Is HClO3 stronger than HBrO3?

HClO3 is stronger compared to HBrO3. This is because the ClO3- ion is more stable than BrO3- ion because the negative charge on oxygen is reduced by stronger backbonding with Cl atom compared to Br atom because of large difference in energy level of Br and O.

Which Oxoacid is strongest?

The strongest acid is perchloric acid on the left, and the weakest is hypochlorous acid on the far right. Notice that the only difference between these acids is the number of oxygens bonded to chlorine.

Which is the strongest acid oxidizing agent among HClO HClO2 HClO3 and HClO4?

Strongest acid should be HClO4 as the conjugate base is highly resonance stabilised by presence of many O atoms. Originally Answered: Which is the strongest acid/oxidising agent among HClO, HClO2, HClO3 and HClO4? Both awards go to HClO4 (perchloric acid).

Is HClO3 stronger than HClO2?

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. … HClO3 (chloric acid) is a stronger acid than HClO2 (chlorous acid) for the following reason.

Which is stronger h2so4 or HClO4?

…it can be predicted that perchloric acid, HClO4, is a stronger acid than sulfuric acid, H2SO4, which should be a stronger acid than phosphoric acid, H3PO4. For a given nonmetal central atom, the acid strength increases as the oxidation number of the central atom increases.

Which is weakest acid?

Oxalic acid is the weakest acid.

Is HCl stronger than HBr?

HBr fumes strongly in moist air. It is one of the strongest mineral acids, with a reducing action stronger than that of hydrogen chloride (HCl).

Is HClO4 stronger than HClO2?

As the number of oxygens increases as you go from HClO to HClO4, the oxidation number of Cl increases. The oxidation number for Cl in HClO is +1, +3 for HClO2, +5 for HClO3, and +7 for HClO4. … This is why HClO4 will be the strongest acid.
