The toughest part about titration is adding just enough of the titrant (NaOH, in this case). If you add the NaOH too quickly, you will likely end up adding too much ("overshooting the endpoint"). Alternatively, you could add it very slowly, drop-by-drop, but with this approach, you'll probably run out of time in the lab! The best option is to know in advance a rough idea of how much you'll need to add. Get close to this amount, then slow down and start adding NaOH in drop-fashion. Considering that the NaOH should be within a few percent of 0.30 M, what volume (in mL) would you expect to use for your third trial with 0.7943 g of KHP? Round your answer to 2 sig figs. Record this volume on your Cover Page and refer to it when performing your titration in Part 1.

Question
The toughest part about titration is adding **just enough** of the titrant (NaOH, in this case). If you add the NaOH too quickly, you will likely end up adding too much ("overshooting the endpoint"). Alternatively, you could add it very slowly, drop-by-drop, but with this approach, you'll probably run out of time in the lab! The best option is to know in advance a rough idea of how much you'll need to add. Get close to this amount, then slow down and start adding NaOH in drop-fashion. Considering that the NaOH should be within a few percent of 0.30 M, what volume (in mL) would you expect to use for your third trial with 0.7943 g of KHP? Round your answer to 2 sig figs. Record this volume on your Cover Page and refer to it when performing your titration in Part 1.
