- why we use methyl orange as indicator in titration of strong base with weak base and not the phenolphthaleinList the observations of a manual titration experiment and explain your expectations. This should include color change and when the equivalence point (endpoint) might be reached. When do you stop and why.What would be an appropriate indicator to use to measure the endpoint volume for a titration with a pH of 4.32 at the equivalence point?
- Explain why the indicator cresol red changes color when the pH is lowered from 10 to 6. What colors will be observed at pH 10, 8, and 6? Why does the color transition require ,2 pH units for completion?In the titration of 50.00mL of 0.2980M HCl, 71.93mL of 0.2173M NaOH was required to reach the phenolphthalien endpoint. Calculate the percent error between the predicted amount and the experimental amountHow is the equivalence point determined in potentiometric titrations? Please explain briefly.
- What is the purpose of heating a sample prior to analysis (regarding potentiometric titration).During the titration of acetic acid solution with standard NaOH using phenolphthalein, the end point was read when the color of the solution was red. How does the reported value of the molarity of acid compare with the actual value?Ideally the pink color at the end point of any titration should be pale pink. But if they are all the same shade of dark pink, that is acceptable.
