1. WHy is KHC8H4O4 used as the acid in standardization titration?
It is relatively inexpensive and can be obtained in essentially 100% purity.
2. Why should you not shake KHC8H4O4 (Acidic solution) before titrating it with NaOH (Basic solution)?
Air contains a small amount of CO2 and you don't want that to dissolve in the solution because it will change the molarity of the standardizing material.
3. Why is boiled distilled waster used to prepare acidic and basic solutions?
Boiling water (and letting it cool) drives any dissolved CO2 out of the water
