Question

A student withdraws 3.00Ml of supernate from a saturated solution of KHC8H4O4 at room temp (22C). This sample was titrated to the henolphthalein endpoint and 12.85mL of 0.0997 M NaOH was required

A similare tiration was done at 22C for a saturated solution of KHP in 0.500 M KCl. The withgrawn supernant was 5.00mL. The volume of titrant (0.0997M NaOH) used was 11.75.

a) calculate the % decrease in solubility by using this equation

%decrease = [HC8H4O4]water - [HC8H4O4]sat'd KCl /[HC8H4O4]water
