Why is HI more acidic than HCl? - Quora

WebHydroiodic acid (sometimes referred to as hydriodic acid) is an extremely acidic solution of hydrogen iodide and water. This compound is known to be the second strongest acid of hydrogen and a halogen (the strongest being hydrostatic acid). Hydroiodic acid is a widely used chemical reagent. WebStrong acids (such as HCl, HBr, HI, HNO₃, HClO₄, and H₂SO₄) ionize completely in water to produce hydronium ions. The concentration of H₃O⁺ in a strong acid solution is therefore equal to the initial concentration of the acid. For example, a solution of 0.1 M HNO₃ contains 0.1 M H₃O⁺ and has a pH of 1.0. Created by Jay. Web33 rows · Acid with values less than one are considered weak. 3.
