To determine which metal can liberate hydrogen gas from steam, we refer to the reactivity (activity) series of metals.

In the activity series, metals that are above hydrogen can displace it from water or acids. However, not all metals above hydrogen can displace it from steam — only those above iron generally react with steam to release hydrogen gas.

Here's a simplified breakdown:

Metals like potassium, sodium, calcium react with cold water.

Metals like zinc, iron react with steam to produce hydrogen gas.

Metals like copper, silver, gold do not react with water or steam.


Now let's analyze the options:

A. Iron – reacts with steam to form iron oxide and hydrogen gas. [Correct]

B. Copper – does not react with steam.

C. Tin – is below iron and reacts very weakly with steam, if at all.

D. Lead – is also below iron and does not react with steam under normal conditions.


Answer: A. Iron
