a. the mass of khc8h4o4 is measured to the nearest milligram; however, the volume of water in which it is dissolved is never of concern water is even added to the wall of the erlenmeyer flask during the titration. explain why water added to the khc8h4o4 has no effect on the data, whereas water added to the naoh solution may drastically affect the data.

Ans : You know the mass of KHC8H4O4, therefore you know the moles of it. No matter how much water you add to the KHC8H4O4 the number of moles will never change. However, if you add water to NaOH that changes the concentration which would effect the number of moles used titrating.
