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. WebpH = −log ([H +]) The formula for pH is shown above. pH is defined as the negative log base 10 of the hydronium concentration. The pH is a logarithmic measure of the concentration …

WebSo if we find the half equivalence point and we go over to where this intersects with the y-axis, the pH at this point should be equal to the pKa value for the more acidic proton. So looking at the y-axis here, it looks like it's a little bit over two. And in reality, the value of pKa one is equal to 2.34. WebJan 30, 2024 · The lower the pH, the higher the concentration of hydrogen ions [H +]. The lower the pKa, the stronger the acid and the greater its ability to donate protons. ... At half the equivalence point: pH = pKa It's worth noting sometimes this equation is written for the K a value rather than pKa, so you should know the relationship: pKa = -logK a.
