Question 1
During a titration of acetic acid with sodium hydroxide, you observe no color change with phenolphthalein. Why might this be problematic?
π‘ Hint: Consider whether the equivalence point is reached before phenolphthalein's transition.
Question 2
A student is comparing the pH transition ranges of methyl orange and phenolphthalein. Which indicator would be more suitable for a titration with a pH range of 3 to 4, and why?
π‘ Hint: Examine where each indicator operates effectively.
