Phenolphthalein is a common pH indicator used in acid-base chemistry. But the history behind this compound is stranger than fiction! It was originally developed as a synthetic dye to compete with mauvine in the late 19th century. It was never used as a dye due to its pH sensitivity, which led to widespread use as a pH indicator. Phenolphthalein will change from colorless to pink once the pH is above 8, making it an ideal indicator for acid-base titrations. This color changing property also led t

SOLVED:A student carried out two titrations using a NaOH solution of unknown concentration in the buret. In one titration she weighed out 0.2458g of KHP (see p. 152) and transferred it to an Erlenmeyer flask. She then added 20.00 mL of distilled water to dissolve the acid. In the other titration she weighed out 0.2507 g of KHP but added 40.00 mL of distilled water to dissolve the acid. Assuming no experimental error, would she obtain the same result for the concentration of the NaOH solution?
