In a strong acid-strong base titration, the equivalence point is … WebbThe two titration curves shown above are produced when the conical flask contains a weak base. The pH of the solution starts above 7 as it is initially basic. The pH decreases as acid is added from the burette. However, the rate of decrease shortly decreases (flattens) due to the formation of a buffer.

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.

WebbIn simple acid-base titrations a pH indicator may be used, such as phenolphthalein, which becomes pink when a certain pH (about 8.2) is reached or exceeded. Another example is methyl orange, which is red in acids and yellow in alkali solutions. Not every titration requires an indicator. WebbTitrations are often recorded on graphs called titration curves, which generally contain the volume of the titrant as the independent variable and the pH of the solution as the …
