Consider the following indicators and their pH ranges:
Methyl orange
3.2-4.4
Methyl red
4.8-6.0
Bromothymol blue
6.0-7.6
Phenolphthalein
8.2-10.0
Alizarin yellow
10.1-12.0
Assume an indicator works best when the equivalence point of a titration comes in the middle of the indicator range. For which of the following titrations would methyl red be the best indicator?


◦ 0.100 M HNO3 + 0.100 M KOH
◦ 0.100 M aniline (Kb = 3.8 × 10–10) + 0.100 M HCl
◦ 0.100 M NH3 (Kb = 1.8 × 10–5) + 0.100 M HCl
◦ 0.100 M HF (Ka = 7.2 × 10–4) + 0.100 M NaOH
◦ 0.100 M acetic acid (Ka = 1.8 × 10–5) + 0.100 M NaOH
