The first marker is if the initial pH is above or below 7. If the pH is above 7, the analyte is either a weak or strong base. If the pH is below 7, the analyte is either a weak or strong acid. dutch oven tisch gas

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.

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.
