Question

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

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

Answer 1

Answer: (B)

400 mL

Answer 2

Law of equivalance (Apply)
equivalance of acid = equivalance of base
$0.1\times v = 0.04\times1$
$v = 0.4\,L$
$= 0.4\times1000 = 400\,ml$
