The reduction of acidified solution of ferric ions by hydrogen gas takes place in the presence of zinc. Explain.

Explanation

To explain the reduction of acidified solution of ferric ions (Fe³⁺) by hydrogen gas (H₂) in the presence of zinc (Zn), we can break it down into the following steps:

### Step 1: Understanding the Reaction
The reaction we are considering involves the reduction of ferric ions (Fe³⁺) to ferrous ions (Fe²⁺) using hydrogen gas. The overall reaction can be represented as:
\[ \text{Fe}^{3+} + \text{H}_2 \rightarrow \text{Fe}^{2+} + \text{H}^+ \]

### Step 2: Role of Zinc
Zinc plays a crucial role in this reaction. Although hydrogen gas itself does not directly reduce ferric ions (Fe³⁺) to ferrous ions (Fe²⁺), zinc facilitates this process.
