WebMar 20, 2024 · pH measures the acidity of the solutions. pH 2 is highly acid and pH 12 is highly basic (alkalyne). You can be sure that the pH of the solution will be intermediate between 2 and 12. Given that the volumen of the two solutions are equal the pH of the resulting combination cannot be so close to the original solutions. WebHowever, it is only an approximation and should not be used for concentrated solutions or for extremely low pH acids or high pH bases. pH = pKa + log ( [conjugate base]/ [weak acid]) pH = pka + log ( [A-] / [HA]) pH is equal to the sum of the pKa value and the log of the conjugate base concentration divided by the weak acid concentration.
