Which acid is stronger HCl or HNO3?
There is so much more to acids and bases than pH and pKa and strong vs. weak. This means HCl in an aqueous solution is more deprotonated than HNO3, and so HCl is a stronger acid than HNO3. That’s it.
Is HCl stronger than h2so4?
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. Additionally, if we look at the pKa value HCl has a pKa of -6.3 and sulfuric acid has a pKa ~-3.
Which of the following is strongest acid HClO4?
Since the identity of the central atom is the same chlorine as is the number of hydrogens compare the number of oxygen atoms. The HClO4 has the most oxygen atoms so it would have to be the strongest acid.
Which is the strongest acid in the following HClO4 HClO3?
Most acidic: HClO4 > HClO3 > HClO2 > HClO. For a series of oxyacids with the same number of oxygens but with different central atoms such as HOBr, HOCl, HOI, as the electronegativity of the central atom increases, the O-H bond strength weakens and the acidity increases.
Is HClO2 stronger than hio2?
In both acid the oxidation number of chlorine and bromine are same ,that is +3 . But chlorine atom is more electronegative than bromine atom . Consequently , HClO2 is more stroger acid than HBrO2 .
Is HIO2 or HBrO2 stronger?
HClO2 is a stronger acid than HBrO2.
Is HBrO3 a strong acid?
There are only 6 strong acids: HClO4 perchloric acid. HNO3 nitric acid. HF (Hydrofluoric acid) is a weak acid, but you can’t store it in glass bottles as it will dissolve the glass. So, no, since HBrO3 and HBrO4 don’t completely dissociate, they are not considered strong acids.
Is HIO3 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.
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.
Why HClO4 is more stable than HClO3?
Greater the number of negative atoms present in the oxy-acid make the acid stronger. The net effect makes it easier from the proton release and increases the acid strength.
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.
Is HBrO3 stronger than H2SeO3?
HBrO3 Is A Stronger Acid Than H2SeO3 H2S Is A Stronger Acid Than HCl H2Se Is A Weaker Acid Than H2S HNO3 Is A Weaker Acid Than HF.
Is H2SO3 or H2SeO3 stronger?
The answer should be HClO4 because its much more electronegative with oxygen atoms. The answer should be H2SO3 because strength of oxoacids of the different elements get depends on electronegativity and increases by it. H2SO3 is the stronger acid since S is more electronegative.
Is H2SO4 stronger than H2SeO3?
Complete answer: Yes, H2SO4 is a stronger acid than H2SO3 . The oxidation state of S is more in H2SO4 which is +7 as compared to +4 in H2SO3 . Greater is the oxidation state of the central atom, the more it attracts the electrons towards itself and also, more it stabilises the conjugate base.
Is HBr or H2Se a stronger acid?
. H2Se, HBr HDr is the stronger acid because Dr is more electronegative than Se so Dr is more stable than HSe-.
Is CH3COOH stronger than ccl3cooh?
Re: Why is trichloroacetic acid stronger than acetic acid? Since the Cl atoms in CCl4COOH are more electronegative than H atoms (in CH3COOH), they pull electron density away from the central carbon atom. This causes the carbon atom to pull electron density from the oxygen in the O-H bond, which weakens the O-H bond.
