WebbTitration curves are the primary means used to graphically represent titration data. There are two types of titration curves, the sigmoidal curve and the linear segment curve. The sigmoidal curves uses the pH of the analyte and the volume of the standard titrate. WebbThe pH at the equivalence point does not equal 7.00 (pH > 7.00) for the weak acid titration. PURPOSE To construct 2 titration curves. One of a strong acid with a strong bases and the other, a weak acid with a strong base. Also to determine the Ka of the weak acid using the constructed titration curve. PROCEDURE Strong Acid Strong Base Titration- 1.

WebbA strong acid-strong base titration is performed using a phenolphthalein indicator. Phenolphthalein is chosen because it changes color in a pH range between 8.3 – 10. It will appear pink in basic solutions and clear in acidic solutions. Neutralization occurs at pH 7.0 as there are equal moles of acid and base.
