Q. Consider titration of $NaOH$ solution versus $1.25 M$ oxalic acid solution. At the end point following burette readings were obtained.
(i) $4.5 mL$
(ii) $4.5 mL$
(iii) $4.4 mL$
(iv) $4.4 mL$
(v) $4.4 mL$
If the volume of oxalic acid taken was $10.0 mL$ then the molarity of the $NaOH$ solution is _______M. (Rounded-off to the nearest integer)

Solution:

$V _{ NaOH }=4.4 ml$

eq. of $NaOH =$ eq. of $H _{2} C _{2} O _{4}$

or, $M \times 4.4 \times 1=1.25 \times 10 \times 2$

or, $M =5.68 M$

$\therefore $ Nearest integer answer is 6
