WebThe equivalence point in a titration occurs at the point at which the concentration of acetic acid and acetate ion are equal. An equilibrium between acetic acid and acetate exists at any pH, and thus some acetic acid will exist in the solution. Hydrogen bonding between acetic acid and acetate prevents all acetic acid molecules from losing a proton. emulatorgames.net shining soulWebMay 2, 2015 · The acid being used has a pKa value So titrating acetic acid (pKa = 4.76) with NaOH, then phenolphthalein (pka = 10) is a good indicator to use since it will be colored after the neutralization reaction is complete. However bromophenol blue (pKa = 4.75) wouldn't work because it would turn blue before the neutralization reaction is complete. dr bell orthopedic jacksonville fl
