What is the first step in the titration method regarding glassware preparation?

Rinsing the burette and pipette with distilled water is an important initial step in the titration process to ensure that the glassware is clean and free from any contaminants that could affect the accuracy of the titration results. This cleaning helps remove any residues from previous experiments and prepares the glassware for precise measurements.

Using distilled water allows for a clean rinse, as it is pure and does not introduce any additional ions or compounds that could interfere with the titration. After rinsing with distilled water, the burette should then be rinsed with the solution that will be added to it, ensuring that any remaining distilled water is displaced and preventing dilution of the titrant.

The other options do not serve as the first step in glassware preparation. Labelling the glassware is important for clarity during the experiment but comes after ensuring they are clean. Fixing the clamp stand to the table is related to setting up the apparatus but does not address the cleanliness of the glassware. Adding solutions to beakers is a subsequent step that follows the preparation and cleaning of the burette and pipette.
