The volume of `0.1 N` dibasic acid sufficient to neutralize 1g of a base that furnishes `0.04` mole of `OH^-` in aqueous solution is :

Options

A. 400 mL
B. 600 mL
C. 200 ml
D. 800 ml

Answer

A

Explanation

Applying law of equivalence
Equivalence of acid = Equivalence of base
`0.1 xx v=0.04 xx 1`
`v=0.4 L=0.4 xx 1000=400 mL`.
