See Answer Question: QUESTION 1 Which indicator would be the best to use if 0.050 M benzoic acid? (Ka = 6.6 × 10–5) is titrated with 0.050 M NaOH? Present calculations to prove your answer. a. WebSo the indicators phenolphthalein (pH range 8.3 to 10.5), methyl red (pH range 4.4-6.5) and methyl orange (pH range 3.2-4.5) are suitable for such a titration. (ii) Weak acid vs. weak base: pH curve of weak acid (say CH 3 COOH of oxalic acid) and strong base (say NaOH) is vertical over the approximate pH range 7 to 11.
