Citric Acid + Sodium → Sodium Citrate + Hydrogen Gas
Explanation:
* Citric acid is a weak organic acid found in citrus fruits.
* Sodium is an alkali metal that is highly reactive.
* Sodium citrate is the salt formed when the sodium ions (Na+) from the sodium metal replace the hydrogen ions (H+) in the citric acid.
* Hydrogen gas is produced as a byproduct of the reaction.
Important Note: This reaction is highly exothermic (releases a lot of heat) and can be dangerous. It should only be performed by trained professionals in a controlled environment.
