Aluminum reacts with hydrochloric acid. Aluminum is extremely reactive and undergoes several reactions. However, if one were to put a piece of aluminum foil in a beaker of hydrochloric acid, there may not be a reaction because of the oxide coating electrolytically applied during production. The reaction will occur with pure aluminum shavings.Know More
When aluminum is placed in a beaker of hydrochloric acid, the reaction produces hydrogen gas and aqueous aluminum chloride. The balanced chemical equation for the reaction is 2Al(s) + 6HCl(aq) = 2AlCl3(aq) + 3H2(g). This experiment can be done safely, but safety goggles should always be worn when working with corrosive acids.
The reaction produces two moles of aluminum chloride and three moles of hydrogen gas. The aluminum donates its valence electrons to become more stable by connecting with chloride. This is a chemical change because aluminum is transformed into a different compound. A chemical change occurs when compounds react to form new compounds. This reaction is known as a single displacement reaction because aluminum trades places with the hydrogen.
Aluminum is one of the most abundant elements on Earth. It comprises approximately 7% of the Earth's crust. The oxide layer that aluminum forms makes the metal resistant to corrosion.Learn more about Atoms & Molecules
Aluminum reacts with oxygen to form a layer of aluminum oxide on the outside of the metal, according to HowStuffWorks. This thin layer protects the underlying metal from corrosion caused by oxygen, water or other chemicals. Aluminum burns in oxygen with a white flame to form the trioxide aluminum (III) oxide, says WebElements. Chemists write the chemical reaction between aluminum and oxygen as: 4Al+ 3O2 = 2Al2O3.Full Answer >
Calcium carbonate reacts with hydrochloric acid to form calcium chloride, water and carbon dioxide. The reaction between these two compounds requires two parts hydrochloric acid to one part calcium chloride. This reaction is fairly rapid and energetic at high concentrations, in large part due to the high affinity of calcium ions for chloride ions.Full Answer >
Copper doesn't dissolve in hydrochloric acid because it does not oxidize easily and has a positive reduction potential, making it fairly unreactive. Copper is also a noble metal, the series of metals which are not affected by non-oxidizing acids.Full Answer >
According to Colorado State University, hydrochloric acid in the stomach kills any bacteria in food. It both attacks proteins directly and activates the pepsin enzyme, which is even more powerful in breaking down proteins. Springfield Technical Community College notes that the acid is released both on food detection and ingestion.Full Answer >
