Question

In a titration, NaOH was added to a burette. The initial reading was 1.2 ml. At the end of the titration, the final reading was 24.8 ml. What was the volume of NaOH that was added?

Answer 1

Final volume less than the initial volume? What is this difference?

Explanation:

Note that burettes are generally calibrated to `0.1` `mL` `+-0.05` `mL`. If your eyes are good you can often estimate the space between the `0.1` `mL` divisions to read say `21.52` `mL` volumes.

As another tip, when I use a burette I always refill the burette to `0` volume; this way I only have to jot down the final figure.
