Why is the 6M NaOH solution diluted before titrating the vinegar sample? How might your results be affected if you used the 6M solution rather than the 0.3M NaOH?

Answer 1

I don't know your experiment, but the usual reason for diluting the titrating solution is so that there is a sensible volume. Looking at your question it looks as though the NaOH at 6M is 20x too concentrated, which means that if you are using 0.3M you will need 20x the volume, which may be more precise to measure.
