For a titration of acetic with sodium hydroxide, which statement regarding indicator suitability is correct?
a. The equivalence point is around pH 2 and the first colour change of thymol blue is expected to be near the equivalence point and is therefore a suitable indicator.
b. None of the provided answers are correct.
c. The equivalence point is around pH 2 and methyl orange is suitable since it changes colour after the equivalence point.
d. The equivalence point is around pH 7 and bromothymol blue is suitable since it changes colour near the equivalence point.
