Here's a breakdown:
* Aluminum (Al) is a reactive metal.
* Hydrochloric acid (HCl) is a strong acid.
Reaction:
2Al(s) + 6HCl(aq) → 2AlCl₃(aq) + 3H₂(g)
Explanation:
* The hydrochloric acid (HCl) provides hydrogen ions (H+) which react with the aluminum (Al) atoms.
* This reaction forms aluminum chloride (AlCl₃) and liberates hydrogen gas (H₂).
* The hydrogen gas bubbles up and escapes into the atmosphere, while the aluminum chloride dissolves in the acid solution.
Observations:
* You will see bubbling as hydrogen gas is released.
* The aluminum will dissolve in the acid.
* The solution will become warmer as the reaction is exothermic (releases heat).
Safety:
* This reaction is exothermic and produces flammable hydrogen gas.
* Always perform this reaction in a well-ventilated area and wear appropriate safety gear.
* Never perform this reaction in a closed container as the pressure from the hydrogen gas could cause an explosion.
