Is H2SO4 more acidic than HBr?
The pH of HBr is 3.01 and that of H2SO4 is 2.75. This would mean that H2SO4 is more acidic having a lower pH but they are not generally compared since H2SO4 is an oxoacid and HBr, a haloacid.
Which is more acidic HCl or HBr Why?
Re: HCl vs. HBr. Due to it’s longer bond length, HBr can completely ionize more easily than HCl, meaning HBr can produce more H+ ions than HCl. Since acid strength is based on the number of protons produce, HBr is stronger than HCl.
Why is H2SO4 more acidic?
Strength or acidity of an acid depends on how easily it loses its proton(s) in aqueous environment. Dissociation constant of H2SO4 (pKa=-3) is more negative than that of HNO3 (pKa=-1.38) that means H2SO4 releases protons more easily than HNO3. Therefore H2SO4 is stronger acid that HNO3.
Which one is more acidic HCl or H2SO4?
HCl is a stronger acid than H2SO4 because a proton more easily separates from chloride ion than from hydrogen sulphate ion and this is reflected in their dissociation constants. The lower the pKa value of an acid the stronger it is. The pKa values of HCl and H2SO4 are -6 and -3 , respectively.
Which is more acidic hi or HBr?
HCl, HBr, and HI are all strong acids, whereas HF is a weak acid. The acid strength increases as the experimental pKa values decrease in the following order: HF (pKa = 3.1) < HCl (pKa = -6.0) < HBr (pKa = -9.0) < HI (pKa = -9.5). Shorter bonds are more stable, and thus the H-F bond is more difficult to break.
Which is more acidic HF or HBr?
HBr, HF HBr is the stronger acid because Br is larger than F. Thus, the H-BR bond is weaker than the H-F bond and Dr- is more stable than F-.
Which acid is strongest or which is most acidic?
More of the number of electron roacetic acid , Cl3COOH having the maximum number of electron withdrawing Cl′s is the most acidic.
Why is H2SO4 more acidic than H2SO3?
We will rank them based on the number of oxygens and hydrogens in the oxoacid. H2SO4 has more oxygens than H2SO3, the additional oxygen will pull electrons towards itself making the O-H bond weaker. H2SO4 is a stronger acid than H2SO3 because b. it had more oxygens to weaken the H-O bond.
Which is a stronger acid H2SO4 or H2SeO4?
H2SO4 is a stronger acid than H2SeO4 because S is more electronegative than Se HIO is a stronger acid than HIO4 because it has fewer oxygens surrounding the.
Why does sulfuric acid react faster than hydrochloric acid?
The concentration of hydrogen ions in the sulfuric acid is greater than the concentration of hydrogen ions in the hydrochloric acid (of the same concentration of acid). Therefore the frequency of effective collisions is greater for the sulfuric acid, leading to a faster initial rate of reaction.
