Balance the equation in acidic medium
`H_(2)S + Fe^(3+) to Fe^(3+) + S + H^(+)`

Explanation

To balance the given redox reaction in acidic medium, we will follow these steps systematically:

### Step 1: Write the unbalanced equation
The unbalanced equation is:
\[ \text{H}_2\text{S} + \text{Fe}^{3+} \rightarrow \text{Fe}^{2+} + \text{S} + \text{H}^+ \]

### Step 2: Assign oxidation states
- In \(\text{H}_2\text{S}\), sulfur (S) has an oxidation state of \(-2\).
