Identify reductant in following reaction. C ₂ O ₄²⁻+ MnO ₄⁻+ H ⁺ Mn ²⁺+ CO ₂+ H ₂ O

Options

AH ⁺
BH ₂ O
CC ₂ O ₄²⁻
DMnO ₄⁻

Correct answer

C. C ₂ O ₄²⁻

Step-by-step solution

+3 C ₂ O ₄²⁻+ +7 MnO ₄⁻ + H ⁺ +2 Mn ²⁺ CO ₂+ H ₂ O The oxidation number of C increase from +3 ( C ₂ O ₄²⁻ ) to +4 ( CO ₂ ) in above reaction. ( C ₂ O ₄²⁻ ) acts as a reductant.
