Question

When sodium reacts with water, the resulting solution is

Accepted Answer

Answer: D. When sodium reacts with water, it forms sodium hydroxide (NaOH) and hydrogen gas (H2). The chemical equation for the reaction is:$$ 2 \text{Na} (s) + 2 \text{H}_2\text{O} (l) \rightarrow 2 \text{NaOH} (aq) + \text{H}_2 (g) $$In words, two moles of solid sodium ($2 \text{Na} (s)$) react with two moles of water ($2 \text{H}_2\text{O} (l)$) to produce two moles of sodium hydroxide in solution ($2 \text{NaOH} (aq)$) and one mole of hydrogen gas ($\text{H}_2 (g)$). The reaction is highly exothermic, meaning it releases a significant amount of heat. Additionally, the hydrogen gas produced may ignite spontaneously due to the heat generated during the reaction.
