From the titration curve below, estimate the "target pH" to synthesize potassium dihydrogen phosphate. 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. ph neutral leather cleaner
