The volume of 0.1 M strong dibasic acid sufficient to neutralize 1g of a base that furnishes 0.04 mole of O H - in aqueous solution is :

Options

  1. A400 mL
  2. B600 mL
  3. C200 mL
  4. D800 mL

Correct answer

C. 200 mL

Step-by-step solution

For neutralisation; ⇒ n o .   o f   m o l e s   o f   H + =   n o .   o f   m o l e s   o f   O H - ⇒ 2 × M a V a = 0.04 ⇒ 2 × 0.1 × V a = 0.04 ⇒ V a = 0.04 0.2 = 0.2   L = 200   mL
