All aqueous solution of oxalic dihydrate contains its 6.3g in 250 ml. The volume of 0.1 N NaOH required to completely neutrilize 10mL of this solution

A

4mL

B

20mL

C

2mL

D

40mL

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Normality of oxalic acid solution `=(6.3xx1000)/(63xx250)=0.4 N`now from`N_IV_I=N_2V_2 ``0.4xx10=0.1xxV_2 ``V_2=40mL`.
