Here's the balanced chemical equation for the reaction:
2 Na(s) + 2 HCl(aq) → 2 NaCl(aq) + H₂(g)
Explanation:
* Sodium (Na) is a highly reactive alkali metal.
* Hydrochloric acid (HCl) is a strong acid.
* When sodium reacts with hydrochloric acid, the sodium atoms lose electrons to become positively charged sodium ions (Na⁺).
* The hydrogen ions (H⁺) from the acid gain electrons to form hydrogen gas (H₂).
* The resulting solution contains sodium chloride (NaCl), also known as table salt.
Observations:
* The reaction is accompanied by the evolution of heat (exothermic).
* Bubbles of hydrogen gas are observed.
* The solution may become warm or even hot.
Caution: This reaction is very exothermic and can be dangerous. It should only be performed under proper safety precautions and in a controlled environment.
