I am filling out my neutralization titration data sheet and i did not understand how to find buret correction (ml) and corrected volume(ml) and Molarity of NaOH without buret correction and as well as with buret correction.

Question

in the lab we have used 50 ml of buret

for KHP mass(g) I got 0.8528g and its titrant volume is 41.70 ml
please help and explain

Answer 1

I assume the buret correction comes from calibration of your buret vs the reading on the buret.
mols KHP = grams/molar mass KHP = ?
mols mols NaOH = mols KHP since the reaction between KHP and NaOH is 1:1.
Then M NaOH = mols NaOH/L NaOH and L NaOH is the buret reading volume or the corrected volume.
