Hbr is a stronger acid than hf
WebKa for hydrofluoric acid, HF, is 7.20×10-4. Ka for hydrocyanic acid, HCN, is 4.00×10-10. What is the formula for the weakest conjugate base; 6. B. Identify the substance that … WebHBr is a stronger acid than H 3 PO 4. This is because HBr completely ionizes in water whereas H 3 PO 4, being a weak acid ionizes only partially. Since, H3PO4 is a weak acid it will form a stronger conjugate base. Explanation: HBr is the stronger acid and has a weaker conjugate base. View the full answer Step 2/4 Step 3/4 Step 4/4 Final answer

H2O, SO2, 02. Answer: a. HF has the highest boiling point among the two substances because of hydrogen bonding a very strong dipole-dipole interaction. b. WebMay 4, 2015 · A. One reason why HBr is a stronger acid than HF is that Br is more electronegative than F. B. One reason why HBr is a stronger acid than HF is that the H-Br bond is weaker than the H-F bond. C. The acids HI and HCI are strong acids in water D.
WebWhy is HF a weaker acid then HCL and HBr? There is a quick answer to this question, and a more involved one. The short answer is that on the basis of acidity trends, the weaker the bond the species has to the proton, the more freely dissociation occurs. WebFluorine is highly electronegative, so the bond in HF is a polar covalent bond. The more polar a bond is, the easier it is to remove the proton or hydrogen from the acid. So, hydrochloric acid (HCl) is a stronger acid than hydrobromic acid (HBr). Based only on its polarity, one might expect HF to be stronger than HCl.
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). Which is stronger HI or h2so4? 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). Hydrochloric acid: Hydrochloric acid is a clear, colorless solution of hydrogen chloride (HCl) in water.
