In the reaction, 2Na + 2H2O → 2NaOH + H2, which substance is the reducing agent? A) NaOH B) H2O C) H2 D) Na
Understand the Problem
The question is asking for the identification of the reducing agent in the given chemical reaction between sodium and water that produces sodium hydroxide and hydrogen gas. To find the reducing agent, we need to determine which substance donates electrons to another substance in the reaction.
Answer
Na
The reducing agent is Na (Sodium).
Answer for screen readers
The reducing agent is Na (Sodium).
More Information
In this reaction, sodium (Na) is the reducing agent because it donates electrons to water (H₂O) and becomes oxidized to sodium ions (Na⁺), which form NaOH.
Tips
A common mistake is confusing the reducing agent with a product of the reaction. Remember, the reducing agent loses electrons and gets oxidized.
