laboratory, using potassium
hydrogen phthalate (KHC3H₂O4,
abbreviated KHP) as the primary
standard. KHP (molar mass=
204.22 g/mol) has one acidic
hydrogen. You prepared solutions
of both NaOH and HCI. It took
22.65 mL of the NaOH solution to
titrate (react exactly with) 1.55 g
KHP. It then took 31.95 mL of HCI
solution to titrate 25.00 mL of the
NaOH solution. What is the
