if air bubbles remain in the burette during the titration, what will the effect be on the calculated values of ::
a- the concentration of NaOh
b- the molarity of H2SO4
It all depends upon when the air bubbles were there, if they changed in size during the titration, or if they were dispensed in the titration.
Go back to the NaOH/H2C2O4 titration did, work up the formulas used to calculate the M of the NaOH and the M H2SO4 and go through the logical sequence.
