Consider titration of NaOH solution versus 1.25M oxalic acid solution. At the end point following burette readings were obtained.
(i) 4.5mL (ii) 4.5mL (iii) 4.4mL (iv) 4.4mL (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)

Text Solution

Verified by Experts

`V_(NaOH) = 4.4 mL`
eq. of NaOH = eq. of `H_(2)C_(2)O_(4)`
or `M xx 4 .4 xx 1 = 1.25 xx 10 xx 2`
or M = 5 68 M
`therefore` Nearest integer answer is 6.
