The solubility product constant of potassium bitartrate (KHC4H4O6) was determined by titrating a saturated
solution of KHC4H4O6 with a standardized solution of 0.025 M NaOH, using phenolphthalein as
indicator. The neutralization reaction is:
HC4H406 (aq) + OH (aq) + C4H4062 (aq) + H2O)
The table below shows the data gathered from the experiment.
Initial buret reading, mL
11.25
Final buret reading, mL
