When sodium reacts with cold water, the primary product formed is sodium hydroxide (NaOH). This reaction also produces hydrogen gas. The balanced chemical equation for this reaction is:

Reaction Overview

The reaction can be summarized as follows:

  • Reactants: Sodium (Na) and water (H₂O)
  • Products: Sodium hydroxide (NaOH) and hydrogen gas (H₂)

Why NaOH?

Sodium hydroxide is a strong base and is formed when sodium reacts with water. While sodium oxide (Na₂O) can form under certain conditions, it is not the primary product in this reaction with cold water. Sodium carbonate (Na₂CO₃) is not produced in this reaction either.

Final Answer

The correct answer is b.) NaOH.
