In the titration of `Fe^(2+)` ions with `KMnO_4` in acidic medium, why is dilute `H_2SO_4` used and not dilute HCI?

Explanation

To answer the question of why dilute \( H_2SO_4 \) is used instead of dilute \( HCl \) in the titration of \( Fe^{2+} \) ions with \( KMnO_4 \) in acidic medium, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Understanding the Role of \( KMnO_4 \)**:
- \( KMnO_4 \) (potassium permanganate) is a strong oxidizing agent. In acidic medium, it can oxidize \( Fe^{2+} \) ions to \( Fe^{3+} \).

2. **Reactions in Acidic Medium**:
...
