An acid-base titration is outlined. • $25.0\text{ cm}^3$ of dilute aqueous alkali is placed in a conical flask. • Indicator is then added to the flask. • Dilute acid is added to the aqueous alkali until the indicator changes colour. • The volume of acid used is then measured. Which piece of apparatus is used correctly?
- AThe $25.0\text{ cm}^3$ of aqueous alkali is measured using a volumetric pipette.
- BThe $25.0\text{ cm}^3$ of aqueous alkali is measured using the lines on the conical flask.
- CThe volume of acid is measured using a measuring cylinder.
- DThe volume of acid is measured using a volumetric pipette.
