What mass of Potassium Hydrogen Phthalate (KHP) will just neutralize 13 mL of 0.20 M NaOH?
(a) Mass of KHP.....................______________________ mg
2) You standardize some sodium hydroxide solution using potassium hydrogen phthalate.
You obtain the following DATA: MASS of "KHP" weighed out: 0.6758 g
VOLUME of NaOH to neutralize "KHP" in A): 10.10 mL
CALCULATE:
(b) The MOLES of "KHP" used......________________
(c) The MOLARITY of the NaOH.....________________
3) You then pipet out a VINEGAR UNKNOWN and titrate it with the standardized sodium hydroxide of 2).
You obtain the following DATA:
VOLUME of VINEGAR titrated: 8.00 mL
VOLUME of NaOH needed to neutralize VINEGAR: 18.51 mL
CALCULATE:
(d) The MOLARITY of the VINEGAR.________________
(e) The WEIGHT/VOLUME % VINEGAR.________________
