Question
In the titration of a strong acid with a strong base, which indicator is most appropriate?
- AMethyl orange (pH 3.1–4.4)
- BPhenolphthalein (pH 8.3–10)
- CEither methyl orange or phenolphthaleinCorrect
- DLitmus (pH 6–8)
Correct answer
Either methyl orange or phenolphthalein
Explanation
Strong acid−strong base titration: equivalence point at pH 7 with a sharp pH jump from ~3 to ~11. Both methyl orange and phenolphthalein fall within this jump. Either works.
