While doing titration, a student recorded a burette reading of 10.0 mL for the neutralization of 10.0 ~mL NaHC ₂ O ₄( aq ) with 0.1 M NaOH ( aq ) . In a separate experiment, 10.0 mL of this NaHC ₂ O ₄( aq ) solution could be completely oxidized by 10.0 mL of KMnO ₄ in an acidic medium. What would be the molarity of KMnO ₄ used by this student?

Options

  1. A0.02 M
  2. B0.04 M
  3. C0.1 M
  4. D0.2 M

Correct answer

B. 0.04 M
