Calculate the number of moles of `Cr_2O_7^(2-)` required to oxidise 1 " mol of "`Fe(HC_2O_4)` in acidic medium. How many moles of NaOH are required to react with 1 " mol of "`Fe(HC_2O_4)`?

Explanation

To solve the question, we need to calculate the number of moles of `Cr_2O_7^(2-)` required to oxidize 1 mole of `Fe(HC_2O_4)` in acidic medium and the number of moles of NaOH required to react with 1 mole of `Fe(HC_2O_4)`.

### Step 1: Determine the oxidation and reduction reactions

1. **Oxidation of `Fe(HC_2O_4)`**:
- `Fe(HC_2O_4)` contains ferrous ion (`Fe^(2+)`) which gets oxidized to ferric ion (`Fe^(3+)`).
- The half-reaction for this oxidation is:
\[
