Chemistry

1. You may have already noticed that the shape of yourspectrophotometric titration curve is quite different than theshapes of the potentiometric titration curves which you haveconstructed in earlier experiments. Why? (HINT: Think about themathematical relationships between pH and concentration andabsorbance and concentration . . .).
2. When performing a potentiometric titration it is veryimportant to make a large number of measurements near the endpoint,while for a spectrophotometric titration one actually ignores themeasurements obtained near the endpoint. Explain.
3. In order for a photometric method to be used for a titration,what requirement(s) must be met by the titration system?
