In an acid-base (neutralization) reaction the indicator will change color at the end point. Select one: True O False
At the equivalence point, you had equal number of moles of acid and base, and the acid was neutralized. You have already calculated this number of moles above. If you had added 5.0 mL less of the 0.10 mol/L NaOH, it would not have been enough base to completely neutralize the acid. a) Determine how many moles of acid would not have been neutralized. b) Determine the concentration of the excess acid that would remain in the flask. (Recall -- the phthalic acid was initially dissolved in 50. mL of water) Volume of 0.10 mol/L NaOH used (mL) (11.2 - 0.0) = 11.2 (22.8 - 11.2) = 11.6 (34.2 - 22.8) = 11.4

a buffer solution is often encountered during the titration of aweak acid. In such a titration, there is a strong base (often sodium hydroxide, as in today’s lab)which is being added to the weak acid. When the strong base reacts with the weak acid, theresult is the conjugate base of the weak acid. It is essential that you not confuse these twobases during the discussion below, and that you write your report so that it is clear which baseyou are talking about. If the pH of the acid solution is monitored during the titration, a pHprofile like the one below can be plotted. For monoprotic acids it will be sigmoid in shape:The Henderson-Hasselbalch equation helps to make sense of this curve (the base referredto is the conjugate base of the weak acid).pH = pKa + log ([base]/[acid])If calculations are desired, two points are particularly important. The first, at the steepest pointof the graph, is the equivalence point. At that point the acid has been completely consumed bythe strong base…
