The equivalent weight of oxalic acid in C ₂ H ₂ O ₄ 2 H ₂ O is

Options

  1. A45
  2. B63
  3. C90
  4. D126

Correct answer

B. 63

Step-by-step solution

The equivalent weight of oxalic acid in C ₂ H ₂ O ₄ 2 H ₂ O is 63. - The molecular weight of oxalic acid ( C ₂ H ₂ O ₄ ) is 90. - But since Oxalic Acid exists with 2 molecules of water, hence molecular weight of Oxalic acid ( C ₂ H ₂ O ₄ 2 H ₂ O )=126 - Now, Equivalent weight = Molecular weight/Basicity - Therefore, Equivalent Weight =126 / 2=63 (As 2 is the basicity) - Basicity here means Oxalic Acid release 2 H ⁺ ions
