1/In experiment #9, we tilt rated sample of KHP with a solution of NaOh. What was the purpose of these tiltration?
2/ you are preparing to perform the tiltrations for experiment#9. Briefly explain why you need to condition the burets?
3/ While performing an experiment, you tiltrated a sample of KHP with NaOH and back titrated with oxalic acid. Using the data below, calculate the normality of the NaOH solution.
final volume (mL) of NaOh: 30.57
final volume (mL) of oxalic acid: 49.21
Initial Volume (mL) of NaOH : 2.27
Initial Volume (mL) of Oxalic acid : 44.23
Mass of KHP: 0.6582 g
Normality of Oxalic Acid: 0.03124 |32 N
