Is hf or hi stronger
WebHydrofluoric acid (HF) is not a strong acid but instead a weak acid. It is classified as a weak acid mainly because it fails to completely dissociate in water. It basically goes against the … WebHCl, 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). Why is HF a weak acid, when the rest of the hydrohalic acids are strong? One might correctly assume that fluorine is very ...
Is hf or hi stronger

WebJun 9, 2024 · HCl, HBr, and HI are all strong acids, whereas HF is a weak acid. Why is HCl the strongest acid? When HCl molecules dissolve they dissociate into H+ ions and Cl- ions. HCl is a strong acid because it dissociates almost completely. In summary: the stronger the acid the more free H+ ions are released into solution. WebAcids become stronger as the X -H bond becomes weaker, and bonds generally become weaker as the atoms get larger as shown in the figure below. The Ka data for HF, HCl, HBr, and HI reflect the fact that the X -H bond-dissociation enthalpy ( BDE ) becomes smaller as the X atom becomes larger. HF. Ka = 7.2 x 10 -4. BDE = 569 kJ/mol.
WebDec 3, 2024 · Since the bond of H and I is easier to break than H and Cl, it is easier for HI to lose H+ and thus it is a stronger acid than HCl.

WebDec 10, 2014 · Re: Why is HI more acidic than HF? The strength of an acid depends on two things: The strength of the A-H bond, and the stability of the resulting anion. Bond strength is related to the length of the bond, and because Iodine has a much larger atomic radius than Fluorine, HI has a much longer, and therefore weaker, bond. WebAug 26, 2014 · Because fluoride is the least stable (most basic) of the halide conjugate bases, HF is the least acidic of the haloacids, only slightly stronger than a carboxylic acid. …

WebDec 1, 2024 · Hi! HCl is a stronger acid than HF because the bond length is longer. A weak acid is classified by its ability to retain H+ and not dissociate into individual ions. HCl has a longer bond length (because Cl has a larger radius than F), so it is easier for the acid to dissociate into H+ and Cl-. It is a general rule that the shorter the bond ... redish waspsWeb33 rows · 1.
