Aluminum Reacting with Hydrochloric Acid

2Al + 6HCl → 2AlCl3 + 3H2

概要

Aluminum reacts with hydrochloric acid to produce aluminum chloride and hydrogen gas. The reaction requires the initial dissolution of the protective aluminum oxide layer, after which it proceeds vigorously. The reaction generates significant heat and rapid hydrogen evolution.
