WebIf you look at a titration curve of phosphate, you'll see a plateau around pH 7.2 ( the pKa of H2PO4-) . This means that at that pH, half the phosphate will exist as you added it, as H2PO4-, and half will exist as HPO4 2-, having acted as an acid and lost a proton.

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. how many sig figs do you use when dividing

"WebWe can calculate the pH at the half equivalence point because we know at the half equivalence point, half of the initial acid that was present has been neutralized and turned into the conjugate base. Therefore, at the half equivalence point, the concentration of weak acid is equal to the concentration of the conjugate base. " - Ph of half and half

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.
