Reaction between sodium hydroxide and aluminium metal
When sodium hydroxide (NaOH) reacts with aluminium metal (Al), the following reaction occurs:
2NaOH + 2Al → 2NaAlO2 + H2↑
Explanation:
- Sodium hydroxide (NaOH) is a strong base and aluminium metal (Al) is a highly reactive metal.
- When sodium hydroxide is added to aluminium metal, a single displacement reaction takes place.
- The sodium ions (Na+) from sodium hydroxide replace the hydrogen ions (H+) in water, resulting in the formation of sodium aluminate (NaAlO2) and hydrogen gas (H2).
- The balanced chemical equation for the reaction is: 2NaOH + 2Al → 2NaAlO2 + H2↑.
Key points:
- Sodium hydroxide reacts with aluminium metal to form sodium aluminate and hydrogen gas.
- The reaction is a single displacement reaction.
- Sodium hydroxide is a strong base and aluminium is a highly reactive metal.
- Sodium aluminate is formed by the displacement of hydrogen ions from water by sodium ions.
- Hydrogen gas is released as a byproduct of the reaction.
Conclusion:
When sodium hydroxide reacts with aluminium metal, sodium aluminate and hydrogen gas are formed. This reaction is commonly used in industries for various purposes such as wastewater treatment, metal cleaning, and as a reducing agent in chemical processes.
