Iron metal is not used for the preparation of hydrogen gas because it is not a reactive enough metal to react with water or acids to produce hydrogen gas. Iron is a relatively stable metal and does not readily react with water or acids at room temperature to release hydrogen gas.
Instead, more reactive metals such as magnesium or zinc are commonly used for the preparation of hydrogen gas. These metals react readily with water or acids to produce hydrogen gas through a chemical reaction.

Iron metal is not used for the preparation of hydrogen gas because of the following reasons:
1. Slow Reaction Rate: Iron reacts very slowly with water or steam to produce hydrogen gas. This slow reaction rate makes it impractical for large-scale production of hydrogen.
2. Formation of Iron Oxides: When iron reacts with water or steam, it forms iron oxides as a byproduct. These oxides can clog the reaction vessels and reduce the efficiency of the process.
3. High Temperature Requirement: The reaction between iron and water or steam requires a high temperature, typically above 1000°C. This high temperature requirement makes the process energy-intensive and expensive.
4. Corrosion Resistance: Iron is a corrosion-resistant metal, meaning it does not react readily with most substances. This property makes iron unsuitable for use in environments where hydrogen gas is produced, as the hydrogen can cause the iron to corrode and deteriorate.
Instead of iron, metals like zinc, magnesium, and aluminum are commonly used for the preparation of hydrogen gas. These metals react more readily with water or steam, producing hydrogen gas at a faster rate and at lower temperatures. They also form fewer byproducts and are more resistant to corrosion in hydrogen-rich environments.
