WebMar 6, 2024 · Since at half equivalence [HA]= [A -] pH = pK a , at half equivalence so Ka = 10 − pH, at half equivalence So you find the equivalent point on the titration curve and read the value of the curve at half of that volume. For this reason you need to collect data half way along the curve (red circle).
