WebJul 20, 2024 · To find the pH we follow the same general procedure as in the case of a weak acid. If the stoichiometric concentration of the base is indicated by cb, the result is entirely analogous to equation 4 in the section on the pH of weak acids; namely, Kb = [OH −]2 cb − [ OH −] Under most circumstances we can make the approximation cb– [OH –] ≈ cb WebMar 18, 2014 · When all of a weak acid has been neutralized by strong base, the solution is essentially equivalent to a solution of the conjugate base of the weak acid. For example, if a 0.2 M solution of acetic acid is titrated to the equivalence point by adding an equal volume of 0.2 M NaOH, the resulting solution is exactly the same as if you had prepared a 0.1 M …

WebMay 2, 2024 · The equilibrium equation yields the following formula for pH: pH = -log 10 [H +] [H +] = 10 -pH. In other words, pH is the negative log of the molar hydrogen ion concentration or the molar hydrogen ion concentration equals 10 to the power of the negative pH value. It's easy to do this calculation on any scientific calculator because more often ... WebTo find pH of a weak base solution, insert concentration (M) and insert Kb value of the weak base (0.001 is input as 1E-3) calculate. pH= See the equation(s) used to make this …
WebMar 23, 2024 · The pH (power of hydrogen) of a solution is a measure of the concentration of hydrogen ions and is also a measure of acidity, but it isn't the same as K a.
