Proper usage of a burette involves several key steps:
Ensure the burette is clean and free from any previous residues. Rinse the burette with the solution to be used, to avoid contamination. Fill the burette above the zero mark and remove any air bubbles by opening the tap briefly. Adjust the liquid level to the zero mark, ensuring no parallax error. Dispense the liquid slowly and steadily, reading the meniscus at eye level for accuracy.
