Sodium reacts vigorously with water to produce

Sodium reacts vigorously with water to produce

  1. Sodium hydroxide (NaOH) and hydrogen gas (H₂) ✓
  2. Sodium chloride (NaCl) and oxygen gas (O₂)
  3. Sodium oxide (Na₂O) and hydrogen gas (H₂)
  4. Sodium nitrate (NaNO₃) and water (H₂O)

Explanation

Sodium reacts violently with water. It forms sodium hydroxide and hydrogen gas. The reaction releases heat and can cause fire.

The equation is 2Na + 2H₂O → 2NaOH + H₂. Never touch sodium with wet hands or throw it in water.

Remember: Sodium floats on water and fizzes. The hydrogen gas sometimes ignites.
