How many moles of `KMnO_4` will be required to react completely with 1 " mol of "`K_2C_2O_4` (potassium oxalate) in acidic medium?

Explanation

To determine how many moles of \( KMnO_4 \) are required to react completely with 1 mole of \( K_2C_2O_4 \) (potassium oxalate) in an acidic medium, we can follow these steps:

### Step 1: Write the half-reactions
1. The oxidation half-reaction for potassium oxalate (\( K_2C_2O_4 \)):
\[ C_2O_4^{2-} \rightarrow 2 CO_2 + 2 e^- \]
Here, each mole of \( C_2O_4^{2-} \) loses 2 electrons.
