KMnO ₄ reacts with ferrous sulphate according to the following equation, Here, 10 mL of 0.1 MKMnO ₄ is equivalent to
Options
- A50 mL of 0.1 M FeSO ₄
- B20 mL of 0.1 M FeSO ₄
- C40 mL of 0.1 M FeSO ₄
- D30 mL of 0.1 M FeSO ₄
Correct answer
A. 50 mL of 0.1 M FeSO ₄
Step-by-step solution
For the reaction, MnO ₄⁻+5 Fe ²⁺+8 H ⁺ Mn ²⁺+5 Fe ³⁺+4 H ₂ O 5 times quantity of Fe ²⁺ consumed than KMnO ₄ . Thus, 10 mL of 0.1 M KMnO ₄ is equivalent to 50 mL of 0.1 M FeSO ₄ .
