25 ml of a solution of barrium hydroxide on titration with a 0.1 molar solution of hydrochloric acid gave a litre value of 35 ml . The molarity of barium hydroxide solution was

Options

  1. A0.14
  2. B0.28
  3. C0.35
  4. D0.07

Correct answer

D. 0.07

Step-by-step solution

Ba ( OH )₂+2 HCI BaCl ₂+2 H ₂ O Applying Molarity equation, M ₁ ~V ₁ 1 ( Ba ( OH )₂ ) = M ₂ ~V ₂ 2 or 25 M ₁= 0.1 35 2 M ₁= 0.1 35 2 25 = 0.7 10 =0.07
