Muriatic acid has many commercial uses in addition to household uses. Depending on the aluminum grade and the acid type, acidic solutions can sometimes remove other substances from aluminum machine parts without damaging the metal. However, due to its corrosive nature, it should only be used when absolutely necessary. Formulas and description of the process Features of hydrochloric acid and aluminum interaction. Share Tweet Send [Deposit Photos] Aluminum is a malleable, light, silvery-white metal. Different aluminum grades react differently to chemicals such as acids. Muriatic acid is a slightly less potent form of hydrochloric acid. Aluminium metal will react with dilute hydrochloric acid to produce aqueous aluminium chloride, "AlCl"_3, and hydrogen gas, "H"_2. However, it’s still extremely caustic and, if used improperly, it can burn skin and clothing, and eat through some metals. Muriatic acid, an extremely strong and corrosive acid, can work to quickly remove what seems impossible. Muriatic acid is a solution of hydrochloric acid (HCl) in water. The acid reacts with other chemicals to remove stains and contaminants. Hydrogen gas is being produced. Certain acid types will not harm some aluminum grades, while other acid types will. The acid has a distinctive pungent smell and is highly corrosive. It is a good electrical conductor. It is also important to ensure all of the acid is rinsed from the wheels once cleaning is completed. How hydrochloric acid reacts with aluminum.
