Question

An aqueous solution of oxalic acid dihydrate contains its 6.3 g in 250 ml. The volume of 0.1 N NaOH required to completely neutralize 10 ml of this solution

• A. 4ml
• B. 20ml
• C. 2ml
• D. 40ml

Answer 1

Answer: (D)

40ml

Answer 2

Normality of oxalic add solution $= \frac{6.3\times1000}{63 \times 250} = 0.4\,N$ Now from $N_{1}V_{1} = N_{2}V_{2}$ $0.4 \times 10 = 0.1 \times V_{2}$ $V_{2}= 40 \,mL$
