Question 8 of 10
You are preparing standard acid and
base solutions for the laboratory, using
potassium hydrogen phthalate
(KHC8H4O4, 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 molarity of the HCI
solution?
