The conjugate base of H2SO4, HSO4-, is very weak, and the molecular structure of H2SO4 is quite stable. In contrast, the conjugate base of HCLO3, ClO3-, is much stronger, and the molecular structure of HCLO3 is less stable.
Why is HClO3 a stronger acid than HClO2?
HClO3 (chloric acid) is a stronger acid than HClO2 (chlorous acid) for the following reason. If we look at the conjugate bases, ClO2(-) and ClO3(-), we find that the negative charge is delocalized over two oxygen atoms in ClO2(-) and over three oxygen atoms in ClO3(-).
What is the difference between HClO3 and H3PO4?
In contrast, the conjugate base of HCLO3, ClO3-, is much stronger, and the molecular structure of HCLO3 is less stable. Finally, the conjugate base of H3PO4, H2PO4-, is somewhere in between the two, and the molecular structure of H3PO4 is also less stable than that of H2SO4.
What is the series of H Cl and O acids?
The series of H, Cl, and O acids are as follows: HClO4 = perchloric acid HClO3 = chloric acid HClO2 = chlorous acid HClO = hypochlorous acid 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.
Which is stronger HClO4 or HBrO4?
Since chlorine is more electronegative than bromine, HClO4 is a stronger acid than HBrO4. Which acid is stronger, HBrO4 or HIO4?
Which is the strongest acid HClO4 HClO3 HClO2 HClO?
And electronegativity of chlorine in turn is directly proportional to the oxidation state of chlorine. Thus, the order of acidic strength is HClO < HClO2 < HClO3 < HClO4 As the number of oxygen atoms attached to chlorine increases, acid strength increase. Hence, the correct option is (2).
Is HClO3 stronger than HClO4?
HClO4 is a stronger acid than HClO3 .
Which is the stronger acid HClO or HClO2?
HClO2 is a stronger acid than HClO.
Why is HClO3 more acidic than Hocl?
- In Chlorous acid, Cl=O. bond will withdraw the electron density from the negatively charged oxygen atom in the conjugate base, so the conjugate base will be more stable and hence the overall acidic strength of Chlorous acid will be more compared to Hypochlorous acid.
Why is HClO stronger than HClO4?
If a proton is less strongly attached to any one of the oxygens, then you get a stronger acid. 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.
Is HClO a strong acid?
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.
Which of the following is the weakest acid a HClO2 B HCl C HClO4 D HClO e HClO3?
HClOThe weakest acid is HClO.
Which one of the following acids is the weakest HClO HBr HClO3 HCl?
HClO acid is weakest.HClO ⇌ H+ + ClO- Which is the weakest out of HF, HCl, HBr and HI?
Which is stronger acid HCl or 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.
How is a stronger acid than HClO?
HNO3 is a stronger acid than HClO3 ; the primary reason is that N is more electronegative than Cl , so it pulls electron density towards itself better. Thus, the H , attached to an outer O , gets less of it and thus the O−H bond is weakened.
Which is more oxidising HClO or HClO4?
The oxiding power of HClO4, HClO3, HCLO2, HClO are in the following order: HClO >HCLO2 >HClO3>HClO4 because the oxidizing power of oxyacids of chlorine is inversely related to the thermal stability of these acids i.e. higher the thermal stability, lower will be oxidizing power of the oxyacid and vice versa.
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.
Which of the following acids is the strongest 2 a HClO4 B HClO3 C HClO2 D HClO E HF?
The HClO4 has the most oxygen atoms so it would have to be the strongest acid.
Is HClO3 a strong acid?
The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only).
