Titration of bases

The target of this project is to construct a general and feasible procedure to determine the acidic equilibrium constants in aqueous solution at 25oC from the data of the potentiometric titration process in a rapid, simple and effective way. Then it will be applied to estimate the equilibrium constants of some new acids.

Solutions and Indicators for Neutralization Titrations A. Standard Solutions: The standards solutions used as titrants for unknown w eak acids or bases are alw ays strong bases or acids, respectively. Standard titrant acids: dilute solutions of HCl, HClO 4 , or H 2 SO 4 . Standard titrant bases: dilute solutions of NaOH, KOH. The primary standards may not be strong acids or bases (e.g., potassium acid phthalate, sodium oxalate, sodium bicarbonate).
