AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
When sodium reacts with cold water, the two products formed are sodium hydroxide (NaOH) and hydrogen gas (H₂).
This is a standard 1-mark factual recall question. Examiners expect both products named clearly. The reaction is: 2Na + 2H₂O → 2NaOH + H₂↑. Note: the source passages do not explicitly state this reaction, but it is standard CBSE Class 10 Chapter 1 content on displacement reactions involving metals and water.
