Question

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

Answer 1

Step-by-step explanation:

Water that is added to the KHC8H4O4 does not have any effect because it does not alter the molar concentration, this is as a result of it being hygroscopic. On the other hand water added to NaOH would have great effect on the molar concentration because of its non hygroscopic nature.
