2. Strong and Weak Acids - Chemistry LibreTexts

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. Sort by: Top Voted Questions Web33 rows · Acid with values less than one are considered weak. 3. The strong bases are listed at the bottom right of the table and get weaker as we move to the top of the table. WebIn such solvents, the acids will be “weak,” and so any differences in the extent of their ionization can be determined. For example, the binary hydrogen halides HCl, HBr, and HI are strong acids in water but weak acids in ethanol (strength increasing HCl < HBr < HI). photomatix camera

WebThus the acid dissociation constant for H 3PO4refers to this equilibrium: The H2PO4−ion, called the dihydrogen phosphate ion, is also a weak acid with its own acid dissociation constant: Thus for so-called polyproticacids, each H+ion comes off in sequence, and each H + ion that ionizes does so with its own characteristic Ka.H3PO4(aq) ⇄ H+(aq) + … WebA) A strong acid has a strong conjugate base. B) A weak base is composed of a cation and an anion with a very weak attraction between them. C) A strong acid is composed of a proton and an anion that have a very strong attraction for one another.
