WebAug 7, 2011 · You can easily get the pH of the solution at this point via the HH equation, pH=pKa+log [A-]/ [HA]. Since [A-]= [HA] at the half-eq point, the pH is equal to the pKa of your acid. If you look at a titration curve, your half-eq point is the flattest part of the cure while the equivalence point is at the steepest part. Web1) The equivalence point of an acid-base reaction (the point at which the amounts of acid and of base are just sufficient to cause complete neutralization). 2) The pH of the solution …

WebMay 17, 2024 · It is due to the fact that at half equivalence point, the pH of the solution is equal to the pKa value of the weak acid. And this pH does not depend on the initial concentration of the acid. You should take into account something that does not appear on your diagrams. The concentration of the strong base (used on the abscissa) is not given !
