Question 21

A student titrates a 25.0 cm³ sample of 0.0800 mol dm^-3 aqueous ammonia with 0.100 mol dm^-3 nitric acid.

Which indicator and what volume of nitric acid are most appropriate to determine the equivalence point of this titration?

Indicator: Methyl orange; Volume: $cm320.0\text{ cm}^3$

Indicator: Phenolphthalein; Volume: $cm320.0\text{ cm}^3$

Indicator: Methyl orange; Volume: $cm331.3\text{ cm}^3$

Indicator: Phenolphthalein; Volume: $cm331.3\text{ cm}^3$
