Number of moles of H + ions required by 1 mole of MnO 4 − to oxidise oxalate ion to CO 2 is ______.

Correct answer

0

Step-by-step solution

The reaction between MnO 4 - ​ with C 2 O 4 2 - ​ is as given below: 2 MnO 4 - + 16 H + + 5 C 2 O 4 2 - → 2 Mn + 2 + 8 H 2 O + 10 CO 2 From this, we can see that 16 moles of H + react with 2 moles of MnO 4 - ​ . Hence, one mole of permanganate requires eight moles of H + ions
