WebH 3 O + concentration and pH value H 3 O + concentration is very low when it compares with weak acid concentration. As an example, if weak acid concentration is 0.1 mol dm -3, H 3 O + concentration may be 0.0001 mol dm -3 . pH of that solution is 4. Web2 days ago · pH = -log [H+] or pH = -log [H30+] The above statement can be rewritten as, [ H30+] = 10^-pH. The pH of a solution can be calculated if the molar concentration of the acid in the solution is known and in turn, the pH value can be used for calculating the Ka value of that solution. Further percentage dissociation may also be calculated as:

If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic. This is known as the p H scale. The pH scale is the range of value s from 0 to 14 that describes the acidity or basicity of a solution. 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.

The hydrated proton is very acidic: at 25 °C, its pKa is approximately 0. The values commonly given for pKa (H3O ) are 0 or –1.74. The former uses the convention that the activity of the solvent in a dilute solution (in this case, water) is 1, while the latter uses the value of the concentration of water in the pure liquid of 55.5 M. Silverstein has shown that the latter value is thermodynamically unsupportable.
