How to take initial points during titration

Ensure the burette is clean, clamped vertically, and filled with the titrant (the solution you are adding) above the zero mark. Open the stopcock briefly to allow the solution to fill the tip and remove any air bubbles. Then, let the solution drain until the bottom of the meniscus is at a readable level, ideally at or below the 0.00 cm³ mark.

Place a white tile or a piece of white paper behind the burette, just below the meniscus. This helps to see the meniscus clearly.

Lower your eye to be level with the bottom of the meniscus. This is crucial to avoid parallax error, which occurs if you read from above or below the meniscus, leading to an inaccurate reading.

Read the volume from the burette scale. Burettes are typically read from top to bottom (0 at the top). Record the reading to two decimal places (e.g., 0.00 cm³, 1.50 cm³, 2.25 cm³). This is your initial burette reading.
