The above chemical equation describes the reaction process between zinc metal (Zn) and water (H2O) to form zinc hydroxide (Zn(OH)2) and hydrogen gas (H2).
- Reaction conditions
This reaction usually occurs at high temperatures. Zn does not react with water under normal conditions but will react when the water is hot or steamy.
- Reaction process
When in contact with water at high temperatures, zinc will react and form zinc hydroxide and hydrogen gas.
Zn(s) + 2H2O(g) -> Zn(OH)2(s) + H2(g)
- Occurring phenomena
When the reaction occurs, we will see gas bubbles being created – that’s hydrogen gas. The initial zinc will gradually be consumed and create a white layer of zinc hydroxide on the surface.
