The diagram shows a burette and conical flask prepared by a student for an acid-base titration.
The student wrote the following method for setting up and using the burette:
"I rinsed the burette with distilled water. With the tap closed, I used a funnel to fill the burette with the sodium hydroxide solution up to the 0.00 cm³ mark. I then opened the tap and ran the solution into the flask until the indicator changed colour."
Give three improvements the student should make to how they prepared and used the burette to ensure an accurate titration.
